Why this score — the assessment, decomposed

The 36.68/100 rests first on Force mass (72.00), Land warfare (72.00), Command & control (65.00). The binding constraints: Air power (8.00), Submarine force (8.00), Nuclear survivability (6.50) — in a causal model, capability can never rise above its weakest observed link. What would move the needle: Air power (8.00) — the weak link in the spending → equipment → readiness → capability chain.

  • Alliance architecture adds a +5.78 bonus.
  • Nuclear deterrence contributes a capped +0.69 bonus — it cannot manufacture top-tier conventional standing on its own.
  • Force mass is capped by what equipment, training and sustainment can actually support — headcount alone scores nothing.

10 of 24 dimensions could not be observed (Equipment quality, ISR & intelligence, Missile forces, Air defense, Cyber & space, Strategic lift…); missing data caps the score — it never inflates it.

Force structure — record

Armed forces

Republic of Sierra Leone Armed Forces (RSLAF): organized as a Joint Force Command with land, air, and maritime components Ministry of Internal Affairs: Sierra Leone Police (2025)

Personnel strength

estimated 10,000 active Armed Forces (2025)

Equipment

the RSLAF has a small inventory comprised of obsolescent or secondhand imported armaments (2025)

Service age & obligation

18-25 for voluntary military service for men and women; no conscription (2025)

Note

the RSLAF’s primary responsibilities are securing the country's borders and territorial waters, supporting civil authorities during internal emergencies, and participating in peacekeeping missions; since 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’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 (2025)

Magna assessment

MILITARY POWER 36.68/100 — The Magna Military Power score is our 0–100 measure of causal military capability — 24 dimensions (mass, equipment, readiness, projection, industry, nuclear deterrence), aggregated through a dependency graph, never by simple addition.

Momentum 0 — Quarterly momentum: the Bureau's read on the country's trajectory over the last quarter, from −10 (deteriorating fast) to +10 (accelerating).

Nothing in Jul–Sep 2026 moved the needle. The institutions functioned, the economy ran its course, and the world looked elsewhere.

That is the honest note: a quarter of normalcy, scored as such.
