Defense analysis is the systematic evaluation of military strategies, capabilities, and threats to ensure national security. It involves assessing various factors, including military technology, intelligence, and geopolitical dynamics, to inform decision-making and resource allocation. Analysts use data and simulations to predict potential conflicts and develop effective responses. This field also encompasses the study of defense policies and budgeting, helping governments prioritize spending on defense initiatives. By understanding the strengths and weaknesses of both friendly and adversarial forces, defense analysts contribute to strategic planning and enhance a nation's ability to respond to emerging threats.
