Standard NATO symbol for an infantry division. The Xs do not replace the division's number; instead, the two Xs represent a division (one would denote a brigade; three, a corps). A division is a large military unit or formation, usually consisting of between 10,000 and 20,000 soldiers. Infantry divisions during the World Wars ranged between 10,000 to 30,000 in nominal strength. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps.
