In military jargon, reconnaissance is abbreviated to recce (in British, Canadian, Australian English) and to recon (in American English), both derived from the root word reconnoitre / reconnoitering.

The types of reconnaissance include patrolling the local area of operations and long-range reconnaissance patrols, which are tasks usually realized in the United States of America by U.S. Army Rangers, cavalry scouts, and military intelligence specialists, using navy ships and submarines, reconnaissance aircraft, satellites to collect raw intelligence; and establishing observation posts. Moreover, espionage is different from reconnaissance, because spies work as civilians in enemy territory.
