Bulgaria — Military Capability Assessment

The 38.32/100 rests first on Alliances (90.62), Command & control (85.00), Combat experience (75.00). 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 +10.00 bonus.
• Nuclear deterrence contributes a capped +0.71 bonus — it cannot manufacture top-tier conventional standing on its own.
• Extreme defense burden applies an economic-strain penalty of −4.00.
• Force mass is capped by what equipment, training and sustainment can actually support — headcount alone scores nothing.

4 of 24 dimensions could not be observed (Missile forces, Air defense, Strategic lift, Expeditionary capability); missing data caps the score — it never inflates it.
