MPR Overview
Sierra Leone ranks 141st in the 2026 Military Power Rankings. The Republic of Sierra Leone Armed Forces (RSLAF) are primarily focused on internal security, disaster relief, and peacekeeping contributions, reflecting the country’s post-conflict orientation following its devastating 1991–2002 civil war. The military remains modest in size, with a structure oriented around national stability, light infantry capabilities, and support to civilian governance.
The RSLAF is organized around land, maritime, and very limited air elements. The Sierra Leone Police remains a separate internal-security service, while the armed forces support border security, civil authorities, disaster response, and regional peacekeeping.
While lacking heavy equipment, combat aviation, strategic air defense, or power projection, Sierra Leone has rebuilt a more professional force through British, U.S., Canadian, French, Chinese, AU, ECOWAS, and UN-linked training and assistance.
While lacking heavy weaponry or strategic force projection, the RSLAF has gained recognition in African Union and ECOWAS peacekeeping roles. Training and reform have been consistently guided by UK-led initiatives, including the International Military Assistance Training Team (IMATT) and subsequent British support missions. The force has developed a strong emphasis on professionalism, community trust, and non-partisan national service.

While the RSLAF lacks conventional warfighting depth, it possesses real-world exposure to irregular conflict, humanitarian deployments, peacekeeping, and post-conflict reconstruction.
Sierra Leone Civil War (1991–2002)
A brutal internal conflict involving the Revolutionary United Front (RUF) and multiple factions led to widespread atrocities. The Sierra Leone Army collapsed early in the war due to corruption and defections. After years of insurgency and failed coups, the British military intervention in 2000 (Operation Palliser) helped stabilize the government. The post-war force was rebuilt under UK supervision, emphasizing demilitarization, discipline, and human rights.
Operation Barras (2000)
British Special Forces rescued hostages held by the West Side Boys militia, a key moment that restored confidence in Sierra Leone’s military partnership with the UK. This operation was a turning point in rebuilding the RSLAF’s legitimacy.
Post-War Military Reform (2002–2010)
With guidance from the IMATT, Sierra Leone dismantled irregular forces and rebuilt the army into a professional, constitutionally accountable institution. Training focused on light infantry tactics, civil protection, and neutrality in political affairs.
Peacekeeping Missions in Darfur, Mali, and Somalia
Sierra Leone has contributed to AU and UN peacekeeping operations, with past deployments including Sudan (UNAMID), Mali (MINUSMA), and Somalia (AMISOM). These missions provided essential operational experience, particularly in asymmetric environments.
Domestic Stability Operations
The military has played a major role in natural disaster response, such as the 2017 Freetown mudslides and Ebola outbreaks, showcasing strong civil-military coordination and national resilience.
While the RSLAF lacks conventional warfighting experience, it possesses valuable real-world exposure to irregular warfare, humanitarian deployments, and post-conflict peacekeeping, making it one of the more ethically grounded and professionally rehabilitated militaries in the West African region.
