Military intelligence (abbreviated MI, int. Commonwealth, or intel. U.S., or G2 U.S.), is a military discipline that focuses on the gathering, analysis, protection, and dissemination of information about the enemy, terrain, and weather in an area of operations or area of interest. Intelligence activities are conducted at all levels from tactical to strategic, during peacetime and in war.
Most militaries maintain a military intelligence corps with specialized intelligence units for collecting information in specific ways. Militaries also typically have intelligence staff personnel at each echelon down to battalion level. Intelligence officers and enlisted soldiers assigned to military intelligence may be selected for their analytical abilities or scores on intelligence tests. They usually receive formal training in these disciplines.
