In Sierra Leone, the RSLAF’s principle responsibilities are securing the borders and the country’s territorial waters, supporting civil authorities during emergencies and reconstruction efforts, and participating in peacekeeping missions; it is small, lightly armed, and has a limited budget; since being reduced in size and restructured with British assistance after the end of the civil war in 2002, it has received assistance from several foreign militaries, including those of Canada, China, France, the UK, and the US; the RSLAF has participated in peacekeeping operations in Somalia and Sudan

the RSLAF’s origins lie in the Sierra Leone Battalion of the Royal West African Frontier Force (RWAFF), a multi-regiment force formed by the British colonial office in 1900 to garrison the West African colonies of Gold Coast (Ghana), Nigeria (Lagos and the protectorates of Northern and Southern Nigeria), Sierra Leone, and The Gambia; the RWAFF fought in both World Wars (2023)
