Methodology

Warhead counts and military spending use public data, while active and reserve personnel, combat aircraft, major naval assets, defense industry, logistical endurance, and combat experience are used as supporting indicators. Land, sea, air, nuclear, cyber-space, asymmetric, and alliance scores are normalized explanatory metrics on a 100-point scale based on public operating range and force density.
