The MPR Algorithm
Explained
Measuring actual warfighting ability today.
The MPR Algorithm is the scoring framework behind Military Power Rankings. It brings the lessons of military history, quantitative measurement and qualitative analysis into a proprietary, real-valued mathematical function. Its purpose is to assess actual warfighting ability today: the strength a country can bring to bear, the destruction it can withstand, and the qualities and weaknesses that shape its performance. Doctrine, readiness, logistics, geography, force posture, strategic depth, industrial endurance and multi-domain combat capability give that assessment its military meaning.
Core Philosophy
The Military Power Ranking (MPR) Algorithm is a scenario-informed, simulation-validated scoring system that quantifies a nation’s ability to win modern wars. It assesses 209 factors grounded in 14 historical categories, covering everything from manpower and weapons systems to command resilience, strategic alliances, and terrain advantages.
What sets MPR apart from legacy rankings is that it does not reward size alone. Instead, it evaluates how a country would perform in the specific kind of war it is most likely to fight. It uses a multi-stage process involving normalization, weighting, qualitative adjustments, strategic modifiers, and a doctrine-based alignment multiplier (WAM).
The goal is to compare military strength in a way that reflects real war conditions. A country with more equipment is not automatically stronger if its forces lack readiness, command integration, sustainment, doctrine, or role fit.
This page explains how MPR turns military data, qualitative analysis, and simulation-informed assessment into a unified military power index.
MPR ranks military power by asking how a force would perform in realistic conflict conditions. The model is built around role, doctrine, combat effectiveness, strategic position, and operational sustainability.
- Role-based: every country has a different mission set and threat environment.
- Combat-focused: scoring is tied to battlefield-relevant capability.
- Doctrine-aware: strategy, training, and command structure affect performance.
- Simulation-informed: scenario analysis helps test assumptions and identify overmatch.
The MPR Military Power Equation
A force must be understood through both what it can do and what it can endure. Destructive strength gives it the means to act; resilience keeps it in the fight. Leadership, training, technology and strategic circumstances can improve its effectiveness, while structural weaknesses can diminish it.
This equation expresses the reasoning behind MPR’s real-valued mathematical function. The full calculation applies factor weights, normalization and mathematical limits. The four terms describe assessed contributions to military power; their relationship cannot be reproduced by adding raw equipment counts to economic figures or judgments about leadership.
Destruction Power — the strength available for use
Destruction Power concerns the forces and weapons a country can actually employ: personnel, land systems, aircraft, naval forces, missiles and other means of delivering military effects. The catalogue assigns 52 factors to this component.
Readiness and deployment capacity determine how much nominal strength can be brought to bear. An aircraft awaiting essential maintenance, a launcher without suitable ammunition or a formation unable to reach the theater cannot provide the capability suggested by its presence in an inventory. These conditions matter before fighting begins.
Weapons also depend on the systems around them. Sensors, targeting, command, trained operators and supporting forces affect what firepower can accomplish. The other equation components explain the support, quality and constraints that shape its use.
Explore domain scoring and the technology and effective firepower factors.
Destruction Tolerance — the capacity to endure and continue
Destruction Tolerance encompasses the material resources, protective systems, national resilience and human endurance that make continued resistance possible. Its 58 factors address the ability to sustain operations, withstand disruption and restore fighting strength as losses accumulate.
Ammunition stocks, usable fuel, spare parts, repair facilities, transport and medical support keep forces functioning. Indigenous production and dependable imports affect replenishment. Geography, defensive preparation, infrastructure resilience and the willingness of institutions and populations to endure hardship shape the demands an opponent must overcome.
Initial stocks and annual production answer different questions. A large stockpile can sustain immediate expenditure; production and imports determine how much can be replaced over time. Similarly, possessing a repair facility is different from being able to recover damaged equipment and return it to service during a campaign.
Explore logistics and sustainment and mobilization and replacement power.
Qualitative Superiority — what makes military strength effective
Qualitative Superiority concerns the leadership, skill, technology, experience, national resources and strategic circumstances that improve military effectiveness. Its 87 factors examine the qualities that help a force turn available means into coherent action.
Sound objectives, competent command, disciplined personnel, intelligence, deception and the ability to adapt can make comparable inventories perform very differently. Economic and technological resources contribute through their practical military application. Alliances matter through the assistance, access and coordination they can actually provide.
Demonstrated capability and potential capability require different evidence. A successful campaign can reveal how forces performed under particular conditions; a new system may have impressive specifications without an equivalent operational record. Experience must be interpreted in relation to the opponent, objectives, conditions and continuing relevance of the methods used.
Explore strategic leadership, force quality and readiness, and demonstrated wartime performance.
Qualitative Inferiority — the weaknesses that diminish power
Qualitative Inferiority identifies the burdens and weaknesses that reduce a country’s usable military power. The catalogue assigns 12 factors to this component. The minus sign expresses their adverse contribution; it does not specify the size of the deduction.
Internal conflict, the burden of hostile neighbors, failed offensives or defenses, force dispersal and constraints on economic or institutional capacity can reduce what is available for a particular military purpose. The demands of offensive objectives also differ from those of defending prepared positions.
The significance of a weakness depends on its scale and context. Several commitments may stretch a force without making every deployed unit unavailable. A past failure can expose a persistent deficiency, but its relevance depends on whether that deficiency remains. The assessment must connect the weakness to its actual military consequence.
Explore force concentration and the qualitative and strategic adjustments.
The four component counts total 209. They describe the catalogue’s subjects, not equal weights or fixed shares of the final score. The fourteen historical categories organize the lessons behind those same subjects.
The Historical Foundation of the MPR Algorithm
MPR took the lessons from all the wars in its database and used them as the foundation for its ranking factors. That research covers significant conflicts from antiquity through 1945, together with MPR’s subsequent study of postwar conflicts. Fourteen recurring influences on the outcome of war provide the historical foundation for the 209-factor assessment.
The historical inquiry connects what each side sought to achieve with the capabilities it possessed, the way those capabilities were used, and the pressures under which the campaign unfolded. A battlefield success is understood in relation to the objectives of the war. The factors carry those lessons into the assessment of present-day forces: whether resources are usable, whether operations can be sustained, and whether military action serves an achievable purpose.
The categories below describe those recurring lessons. Their linked factor lists define the corresponding subjects assessed by MPR today. The lessons guide what is examined; the scoring process explains how the resulting quantitative and qualitative evidence is brought together.
Strategic Leadership and Command
Choosing achievable objectives, making sound decisions, coordinating forces, and connecting battlefield success to the war’s political purpose. Divided command, overconfidence, and pursuing the wrong objectives repeatedly undermine military strength.
Logistics and Sustainment
Keeping forces supplied with food, water, ammunition, fuel, transport, and essential equipment throughout a campaign. Supply disruption, blockade, encirclement, and overextension repeatedly turn strong armies into exhausted or immobilized forces.
Morale, Cohesion, and Political Will
The willingness of troops, leaders, and populations to endure losses and continue resisting. Discipline, loyalty, confidence in leadership, and commitment to the cause sustain resistance; panic, betrayal, and political disintegration can collapse forces that retain substantial material strength.
Doctrine, Tactical Execution, and Adaptability
How effectively forces fight together, respond to unfamiliar threats, and learn from experience. Combined arms coordination, flexible formations, and adaptation repeatedly overcome rigid methods or poorly coordinated attacks.
Intelligence, Reconnaissance, and Deception
Understanding enemy intentions, positions, capabilities, and vulnerabilities while protecting or disguising one’s own plans. Accurate information creates opportunities; its value depends on commanders acting effectively upon it.
Economic Capacity, Mobilization, and Replacement Power
The ability to produce equipment, mobilize manpower, replace losses, and rebuild fighting strength. This becomes especially influential as wars lengthen: an army can win engagements while exhausting resources it cannot replace.
Geography, Terrain, and Defensive Preparation
Mountains, rivers, straits, cities, distance, fortifications, and defensive depth shape which forces can fight effectively. Favorable ground and engineering can restrict an opponent’s numbers, mobility, and firepower.
Alliances, Diplomacy, and External Support
Reliable allies provide additional forces, supplies, access, and pressure on other fronts. Their contribution depends on shared objectives, timely assistance, and coordination; defections or strategic isolation can overturn a military position.
Force Quality, Training, and Readiness
The proficiency and preparedness of soldiers, crews, officers, and formations. Experience, disciplined fire, reliable communications, and competent junior leadership determine how much usable combat power a force actually possesses.
Force Concentration and Reserve Employment
Bringing sufficient effective strength to the decisive location and committing reserves at the right moment. Overall numbers matter, but dispersed forces, delayed reinforcements, or exhausted reserves can leave the critical sector vulnerable.
Control of Sea Lanes, Airspace, and Strategic Routes
The ability to move, reinforce, supply, and project force while restricting the enemy’s access. Maritime and aerial control can determine whether an invasion, overseas expedition, or prolonged campaign remains possible.
Technology and Effective Firepower
Advantages in weapons, range, protection, accuracy, sensors, and destructive power. Their influence depends on deployment, trained operators, supporting doctrine, and the enemy’s ability to develop countermeasures.
Mobility, Initiative, and Exploitation
Moving quickly, setting the pace of operations, and exploiting success before the enemy recovers. Speed can create surprise and disrupt coordination, provided advancing forces retain supplies and mutual support.
Weather, Disease, and Physical Endurance
Rain, mud, cold, heat, illness, and fatigue affect movement, supply, equipment, and fighting capacity. These conditions can become decisive when one side is substantially better prepared or adapted.
From Historical Lessons to Present-Day Assessment
The fourteen categories organize the reasons military forces succeed or fail. Destruction Power, Destruction Tolerance, Qualitative Superiority and Qualitative Inferiority describe how the factors contribute to the overall assessment. The first concerns the power a country can employ; the second, what it can withstand and sustain; the third, qualities that improve military effectiveness; and the fourth, weaknesses that diminish it.
These relationships cross category boundaries. Logistics keeps destructive power available, leadership determines its employment, and morale helps sustain resistance. A weapon’s numerical strength, its readiness and the means to maintain it describe different parts of its military value. Their relationship must be understood when the factors are interpreted together.
Records of successful and failed offensives and defenses provide evidence across all fourteen categories. These four factors remain within the 209-factor assessment. They describe demonstrated performance whose meaning depends on the objectives, opponents, conditions and continuing relevance of the experience.
Aggregate inventories and service-level assessments remain useful summaries of the underlying capabilities. Total combat aircraft, for example, summarizes the relevant aircraft classes; it does not create an additional class of aircraft. War-alignment results describe an effect of the model’s interpretation. The Factors page explains these summaries alongside the complete catalogue.
Combining the Scientific Method with Predictive Modelling
MPR combines quantitative measurement with qualitative military analysis. Its factors emerge from the study of war: what commanders attempted, what their forces could bring to bear, how those forces were employed, and why resistance endured or collapsed. Regression analysis examines relationships within that evidence, while military judgment connects the measured variables to the circumstances in which they mattered.
The mathematical assessment brings these inputs together in a proprietary, real-valued function subject to mathematical limits. Construct validity, reliability and measurement error are central to interpreting the result. A precise-looking number is useful only insofar as the evidence and reasoning behind it support the military meaning assigned to it.
Regression analysis and the interpretation of war outcomes
Regression analysis examines the relationship between an outcome and explanatory variables. In military analysis, that requires decisions about what constitutes an outcome, which factors are relevant, and how unlike campaigns can be compared without losing their distinctive conditions.
A territorial gain, the preservation of an army, successful defense of a homeland and achievement of a political objective are different measures of success. The relationship between resources and results must be interpreted with the purposes of the war in view. Battlefield success and the achievement of the war’s objectives are connected, but they are not interchangeable.
The records of successful and failed offensives and defenses connect the factor catalogue to demonstrated performance. They remain evidence to interpret alongside the opposing forces, terrain, external support, duration and objectives. A result does not, on its own, identify the particular cause that produced it.
Regression offers a way to examine patterns in the evidence. Its interpretation depends on the observations, variable definitions and model being used. Least-squares fitting can be sensitive to unusual observations, and extrapolation beyond the conditions represented in the evidence requires care.
Statistical background: NIST, linear least-squares regression. This explains the statistical method, not the validation of MPR’s proprietary model.
The real-valued function, normalization and weighting
A real-valued function produces a numerical result from its inputs. MPR’s public military power equation identifies four conceptual contributions to that result. The factor definitions establish what is assessed; normalization establishes a comparable scale; weighting expresses relative military significance; adjustments account for qualitative and strategic conditions.
These steps answer different questions. A normalized value of 0.5 can express half of a reference quantity. It does not establish half the military effect. A factor’s numerical size, its practical usefulness and its contribution to the overall assessment must be distinguished.
Mathematical limits constrain the way contributions enter the assessment. The public equation explains the structure of the reasoning; it does not disclose the complete function, its coefficients or internal limits. The seven-stage explanation develops the published scoring process without treating a conceptual expression as a complete numerical implementation.
Construct validity, reliability and measurement error
Construct validity concerns whether the interpretation of the assessment supports what it is intended to measure: actual warfighting ability today. Counting owned equipment is not sufficient if the intended measure concerns equipment that can be employed, supported and coordinated in a real campaign.
Reliability concerns consistency and precision under comparable conditions. It is distinct from validity: a method can produce consistent results while omitting an important part of the military question. Random measurement error and systematic bias must also be distinguished; collecting more observations does not automatically remove a consistent error in definitions or assumptions.
For MPR, the practical questions include whether inventories have compatible definitions, whether a quantity refers to active or stored equipment, whether the reference dates are comparable, and whether an assessment confuses procurement ambitions with available capability. Qualitative judgments require a consistent meaning and evidence appropriate to that meaning.
Measurement concepts: AERA/APA/NCME Standards (2014), pp. 11 and 33–34. These are general measurement principles, not an external certification of MPR.
Measured quantities, informed estimates and unavailable information
The evidence varies by subject. Some quantities are documented directly; others require estimates from compatible sources or qualitative assessment. A published inventory, a readiness estimate and a judgment about command competence are different kinds of evidence and should retain those distinctions.
Estimates need a clear definition and reference date. Where public evidence is incomplete, the absence of a reported quantity does not establish the absence of a capability. Equally, an announced programme does not establish that an operational capability is already available. The source library and country profiles provide the supporting context.
Operational, training, reserve, stored, ordered and developmental systems can have very different present military significance. Keeping those distinctions visible protects the meaning of the assessment. Uncertainty cannot be resolved simply by printing a more precise number.
The 209 MPR Factors
MPR evaluates countries across 209 factors. These factors cover the major inputs that shape modern military power. Each has a defined subject and contributes according to its military significance; the number of factors in a category does not determine that category’s weight.
- Ground, air, naval, missile, and special operations capability.
- Cyber, electronic warfare, space, intelligence, and command systems.
- Logistics, sustainment, mobilization, and strategic reach.
- Doctrine, training, morale, force integration, and combat experience.
- Geography, terrain, infrastructure, alliances, and national resilience.
Each factor is weighted by operational importance, role fit, and likely effect under real conflict pressure.
Example: a large tank force may have limited value in terrain where armor cannot maneuver effectively. A smaller drone force may have high value if it is integrated into doctrine, command systems, targeting networks, and battlefield adaptation.
From National Resources to Usable Military Power
Ready forces and usable ammunition have an immediate military application. Economic output, defense spending, industrial capacity and access to foreign technology contribute through procurement, production, training, maintenance and mobilization. Their military value depends on what has been converted into usable capability and on the demands and duration of the conflict.
A wealthy country may possess considerable replacement potential while lacking a particular munition in the required quantity today. A smaller economy may have prepared substantial stocks for the war it expects to fight. Stocks, annual indigenous ammunition production and reliable weapons imports therefore describe different parts of the capacity to fight and replenish a force.
Related factors, shared causes and double counting
The factor catalogue describes connected parts of military power. Logistics sustains firepower, training improves its employment, and command determines where it is concentrated. The connection between factors is part of the assessment; it does not make them interchangeable or justify counting the same asset twice.
Each of the 209 numbered factors appears once in the catalogue. A factor can inform several historical lessons, but those connections do not create additional factors. Likewise, an aircraft total summarizes the aircraft classes beneath it. Adding both the total and every class as though they were separate fleets would overstate the underlying resource.
The nine retained summary and output measures include aggregate aircraft and helicopter inventories, service-level strength assessments and the diagnostic effect of war-type alignment. They remain useful descriptions without becoming nine further inputs.
Why the mission and the passage of time matter
Defending prepared territory and conducting an overseas offensive impose different demands. Geography, distance, lift, access, allies and doctrine determine which capabilities can participate and what they must sustain. The same fleet or formation can have different military significance in those settings.
Time changes the balance between what is available and what can be replenished. Immediate readiness and accessible stocks shape the opening capacity to fight. Production, imports, repairs, replacement crews and mobilization become increasingly important as a campaign continues. These are connected assessments of current forces and their capacity to endure; an unfulfilled acquisition programme cannot be treated as an available weapon.
Successful and failed campaigns also need a date and context. Their relevance depends on the forces, institutions and methods involved and on what has changed since. Historical experience informs the assessment of present capability rather than making every past outcome a permanent measure of today’s strength.
The Seven-Stage Scoring Process
- 01Raw Data Collection
- 02Data Normalization
- 03Weighted Scoring by Category
- 04Category Aggregation
- 05Qualitative and Strategic Adjustments
- 06Strategic Context Modifiers
- 07War-Type Alignment Multiplier (WAM)
Raw Data Collection
Each nation is assessed using real-world metrics drawn from military databases, defense white papers, satellite imagery, economic indicators, and force structure audits.
The input stage establishes what is being measured before assigning it military significance. Personnel strength, equipment inventories, readiness and the capacity to sustain operations describe different parts of a force. Their definitions and reference dates matter when comparing countries.
Data Normalization
All inputs are normalized to a 0–1 scale using global max-value comparisons:
This ensures comparability across countries of vastly different sizes.
- Vᵢ
- The normalized value for the input being compared.
- Xᵢ
- The country’s value for that input.
- Xₘₐₓ
- The largest reference value for the same input.
In this published normalization expression, a value equal to the reference maximum produces 1; half of that maximum produces 0.5. Normalization establishes a common scale. It does not, by itself, establish equal combat effectiveness or determine a factor’s importance.
Weighted Scoring by Category
Normalized data is weighted based on:
- Historical combat outcome relevance
- Doctrinal value (e.g. offensive vs. defensive warfare)
- Scenario testing
Weights are validated through:
- Past war case studies (e.g. Ukraine, Gulf War, Vietnam)
- Doctrine mapping
- Monte Carlo simulations
Normalization and weighting answer different questions. Normalization makes values comparable; weighting expresses their operational relevance. Doctrine mapping connects a capability to the mission it supports, while scenario testing examines that relationship under specified conflict conditions.
Category Aggregation
Each of the ten capability dimensions described below generates a weighted subtotal. These are then aggregated:
Where C_w is the weight of each category’s relevance to war outcomes.
- Sc
- A category’s weighted subtotal.
- Cw
- The weight assigned to that category.
- Σ
- The sum across the capability categories.
In this framework, the first ten dimensions form the capability assessment; the eleventh, war-type alignment, supplies the final multiplier. The fourteen historical categories describe the lessons behind the factors; they are not fourteen additional subtotals to add to this expression. The category totals and their relevance weights serve different roles; adding inventories without those distinctions would not reproduce the assessment.
Qualitative and Strategic Adjustments
Adjustments are made based on combat cohesion, corruption, morale, civil-military trust, and wartime history.
If a military consistently underperforms in simulations or real wars despite strong quantitative inputs, qualitative downgrades apply.
This stage connects measured resources to the institutions and people expected to use them. Cohesion, leadership continuity, the ability to adapt under pressure and the relationship between political objectives and military execution help explain why similar inventories can produce different results.
Strategic Context Modifiers
Factors such as coalition support, wartime economy, and internal instability are applied to reflect real-world wartime dynamics.
A force operates within a wider strategic system. Access to partners, external supplies, industrial endurance, internal stability and the demands of a prolonged war affect what can be deployed, replenished and sustained.
War-Type Alignment Multiplier (WAM)
This final multiplier adjusts the score based on how well a country’s doctrine and force structure fit the war type in question.
The published alignment examples below illustrate the effect of role fit in this scoring explanation. They are not a universal bonus or penalty for every defensive or offensive operation.
- Defensive doctrine in homeland war: ×1.25
- Offensive doctrine invading entrenched defense: ×0.85
- Critical misalignment (e.g. expeditionary force in jungle terrain): ×0.70 or lower
War-type alignment makes the purpose of a force central to its assessment. A military organized for territorial defense faces different requirements from one attempting distant expeditionary operations. Alignment concerns the relationship between force design and the actual mission, terrain and opponent.
Domain Scoring
MPR assesses performance across major warfighting domains, then normalizes those scores into a unified military power index.
- Ground combat capability.
- Air combat capability.
- Naval combat capability.
- Cyber and electronic warfare readiness.
- Missile, nuclear, and strategic deterrence power.
- Logistics, sustainment, and industrial endurance.
Domain strength is not judged in isolation. MPR also evaluates how well those domains work together in multi-domain operations.
Doctrine and Role Adjustment
Every country is evaluated against its realistic military role. Some forces are designed for expeditionary operations, while others are built for territorial defense, deterrence, regional influence, or asymmetric denial.
- Territorial defense.
- Expeditionary power projection.
- Asymmetric denial.
- Strategic deterrence.
- Regional stabilization and alliance support.
A force is rewarded when its structure, doctrine, geography, alliances, and readiness match the mission it is most likely to face.
The Analytical Dimensions and Their War-Type Alignment

Simulation-Informed Analysis
MPR uses scenario analysis and simulation-informed modeling to test how military strengths translate into likely outcomes. These scenarios help identify which capabilities matter most in different conflict types.
- How forces perform in likely regional scenarios.
- How terrain, distance, logistics, and escalation shape outcomes.
- How doctrine and command systems affect battlefield coordination.
- How overmatch, resilience, and endurance change over time.
Example: layered air defense may outperform larger aircraft numbers if the defending force has better integration, terrain advantage, radar coverage, missile depth, and command discipline.
Role of Simulation in the MPR Model
Simulations are used at multiple stages to verify realism:
- Validate weighting logic
- Test scenario outcomes
- Recalibrate misaligned scores
Simulations involve:
- Defined conflict scenarios (who, where, why, how)
- Doctrinal role assignments
- MPR data imports (adjusted for terrain, command, etc.)
- Monte Carlo iterations to model outcome probabilities
Results feed back into the scoring model to improve prediction accuracy.
The Final Score
The result is a single predictive combat value:
It is not an index of weapons or manpower, but a scenario-aligned forecast of real combat effectiveness.
- Scontext
- The score after qualitative and strategic-context adjustments.
- WAM
- The War-Type Alignment Multiplier.
The equation connects the context-adjusted assessment to the fit between a country’s military design and the conflict being considered. The scenario, objectives and conditions remain essential to interpreting the result.
Why MPR Differs From Count-Based Rankings
Count-based rankings often overvalue raw inventory and undervalue the factors that decide whether military power can actually be used. MPR places more weight on integration, readiness, sustainment, doctrine, geography, and combat relevance.
- Raw equipment totals do not equal combat power.
- Budget size does not automatically translate into readiness.
- Modern warfare depends on domain integration and sustainment.
- Geography, alliances, and strategic depth can change outcomes.
MPR asks a harder question: can a military fight, survive, adapt, and achieve its objectives under real operational pressure?
Why MPR Matters
Unlike conventional military rankings, MPR answers the question:
"If these two countries fought under realistic conditions, who would win — and why?"
It is the only model that combines:
- Normalized global data
- Scenario-based doctrine alignment
- Real-world combat simulations
- Strategic and qualitative context
This makes MPR the most realistic and predictive global military ranking system available today.
The Ranking Model and the Public Tools
The ranking framework, the force-comparison display, the interactive War Simulator and the detailed scenario analyses serve different purposes.
Global rankings
The ranking table presents MPR’s comparative assessment. Its score and index columns express military power within the ranking framework.
Explore the rankingsForces comparison
Compare personnel and equipment inventories, individually or in coalitions. Inventory comparisons help establish force structure; they do not by themselves establish joint combat effectiveness.
Compare forcesInteractive War Simulator
The public calculator compares standardized MPR scores, offers Monte Carlo trials, and applies its stated defensive-stalemate rule. It does not independently recalculate every geographical, doctrinal or logistical factor when countries are selected.
Open the War SimulatorDetailed scenarios
The scenario library examines particular matchups, objectives, geography, force posture, intervention and escalation. This is where the circumstances of a conflict become central to its interpretation.
Read the scenariosFinal Word
The MPR Algorithm is built to make military power analysis more transparent, realistic, and useful. It does not treat all countries as if they have the same mission, geography, doctrine, or strategic constraints.
MPR rankings are shaped by combat capability, doctrine, readiness, logistics, geography, strategic depth, and simulation-informed analysis. That is why the MPR system is designed to measure usable military power, not just visible military size.
