Methodology
The Warfare Institute Strength Index scores 145 nations out of 100 on deployable force. Each category is normalised against the strongest nation, adjusted for equipment quality and upkeep, and multiplied by electronic-warfare and command-and-control enablers.
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.

Equipment quality and readiness
Where model inventories are available, the index uses units multiplied by model effectiveness rather than treating all equipment as interchangeable. Availability estimates and command-and-control and electronic-warfare factors affect deployable strength. Public estimates can be incomplete or uncertain.
What the index does not predict
A higher score does not establish who would win a war. Terrain, distance, supply lines, alliances, operational objectives and leadership affect outcomes. Alignment camps and wartime status are contextual displays, not additional numerical ranking inputs.
Dates and traceability
The ranking year is an edition label. Equipment rows retain their own data dates and source tags; some model counts are reconciled to aggregate inventories. See the source registry for the source families and the corrections process for reporting discrepancies.
