Military Forces

As a noun the military usually refers generally to a country's armed forces or sometimes, more specifically, to the senior officers who command them. In general it refers to the physicality of armed forces, their personnel, equipment, and physical area which they occupy.
As an adjective military originally applied only to soldiers and soldiering, but it soon broadened to apply to land forces in general and anything to do with their profession. The names of both the Royal Military Academy (1741) and United States Military Academy (1802) reflect this. However, at about the time of Napoleonic Wars "military" began to be applied to armed forces as a whole and in the 21st century expressions like "military service", "military intelligence" and "military history" reflect this broader meaning. As such, it now connotes any activity performed by the military personnel.
