A battalion is a military unit. The use of the term battalion varies by nationality and branch of service. Typically a battalion consists of 300 to 800 soldiers and is divided into a number of companies. A battalion is typically commanded by a lieutenant colonel. In some countries the word battalion is associated with the infantry. The term was first used in Italian as battaglione no later than the 16th century.
Re: How many soldiers make an army unit? I *used* to know quite a bit about small-unit (i.e., squad or section level) TO&E for WWII, but long neglect of the topic dims memory. In case it's of interest: some nations deviated quite a bit from the average 10-or-so man rifle squad.
