Aims and scope

The Military Balance is The International Institute for Strategic Studies' annual authoritative assessment of the military capabilities and defence economics worldwide. It is an essential resource for those involved in security policymaking, analysis and research. Detailed A-Z entries list each country’s military organisation, personnel members, equipment inventories, and relevant economic and demographic data. Regional and select country analyses cover the major developments affecting defence policy and procurement, and defence economics. The opening graphics section displays notable defence statistics, while additional data sets detail selected arms orders and military exercises, as well as comparative defence expenditure and personnel numbers. The Military Balance is an indispensable handbook for anyone conducting serious analysis of security policy and military affairs.


“Amid continuing conflict and broadening insecurity, The Military Balance provides essential facts and analysis for decision-makers and for better informed public debate.”
Dr Robert M. Gates, former U.S. Secretary of Defense and Director of Central Intelligence


“Because military affairs are inevitably clouded in fog, the IISS Military Balance is an essential companion for those who seek to understand.”
Lord Robertson of Port Ellen, former UK Defence Secretary and Secretary-General of NATO
