Faisal asked: I am a 16 year old boy and I want to know what exactly is defense analysis and whether military analysis and defense analysis are the same thing?

S. Kalyanaraman replies: Defence Analysis and Military Analysis are one and the same thing. The word 'defence' came to be increasingly used during the course of the 20th century, instead of the earlier preference for 'war' which is seen as indicating an offensive mentality. Thus, for instance, Ministries of War became Ministries of Defence. As a subject, Defence Analysis relates to the study of military concepts, military organisation and structures, and military technologies. Military concepts guide the use of armed forces and their weaponry as well as the strategies and tactics used in various contingencies like all-out war, limited war, intervention in a third country, counter-insurgency, peacekeeping operations, etc. Military organisation refers to how the armed forces are structured to meet the requirements laid out by a particular defence policy. And military technologies are those developed and used to increase military power.
