Military expenditure refers to the financial resources allocated by a government for the maintenance and development of its armed forces. This includes spending on personnel salaries, equipment, training, and operations. Countries often adjust their military budgets based on security needs, geopolitical situations, and economic conditions. Governments track military expenditure to ensure national defense and readiness. Organizations like the Stockholm International Peace Research Institute (SIPRI) provide data on global military spending, allowing for comparisons between nations. High military expenditure can reflect a country's strategic priorities, while lower spending may indicate a focus on other areas, such as social programs or infrastructure.
