Provisional ranking: air superiority, land forces, naval forces, logistics, active manpower and financials. Strike and air defense are not scored until comparable measurements cover every country. Registered reserve totals are shown but excluded from manpower. The top 20 carry a small adjustment (about ±7%) for war production, national will, covert/cyber record and strategic depth; other countries stay neutral until assessed. Methodology
