The regiment is the normal unit for the tactical employment of German parachute troops. Each regiment is divided into three battalions, and each battalion into three rifle or light companies and one heavy weapons company (machine-gun and mortar company). Special armament, consisting of 75-mm infantry guns and 37-mm antitank guns, is provided in the regiment for two special companies which by analogy with American nomenclature may be called the cannon company and the antitank company. The organization of the German parachute regiment is said to have been mainly determined by the carrying capacity of the JU-52, the airplane ordinarily used in transporting parachute troops. The men are usually moved by units, a platoon of 36 men being transported in a flight (Kette) of 3 planes.
