Command 

(1) A temporary or permanent troop organization (team) with 3 or more men, designated to perform particular services or other duties.

(2) An order of the commander (senior man) expressed in concise form precisely as defined by the military regulations and manuals. A command is subdivided into the cautionary and executory parts. In the command “Squad, to the attack—forward!” the first words are cautionary and the last word, “forward,” is the executory part. Commands may also consist of nothing but the executory part, such as “Attention” and “At ease.”
