Detachment (military) in the context of "Delta Force"

In military terminology, an outpost is a location where detachments of military personnel are stationed at a distance from the main armed force or formation in a region. Outposts are usually located in remote or sparsely populated areas, positioned to observe and defend against unauthorized intrusions and surprise attacks, serving as the first line of defense. The station occupied by such troops, usually a small military base or settlement in an outlying frontier, limit, political boundary or in another country. Outposts can also be called miniature military bases based on size and number of troops it houses. Oldest known use is from the 16th century "station when on duty, a fixed position or place," 1590s, from French poste "place where one is stationed,"
