military

adj. of or pertaining to the military; befitting or characteristic of a soldier; performed by the defense force of a nation

n. army, armed forces, defense force of a nation

Military has two broad meanings. In its first sense, it refers to soldiers and soldiering. In its second sense, it refers to armed forces as a whole. Over the years, military units have come in all shapes and sizes. They have been as small as a handful of medieval peasants banded together for battle under their feudal lord or as large as the invasion force created in 1944 for D-Day. They can be as rigidly organized as the impis of Shaka Zulu or virtually autonomous like the Knights Templar during the Crusades. Some states - for instance, Sparta or more recently Prussia - have even placed military prowess at the heart of government.
