World War II

The conflict that produced general-purpose light machine guns, mass-issued SMGs and the first assault rifle (StG 44).

Context and course

The Wehrmacht inaugurated the general-purpose machine gun concept with the MG34 and MG42 (900–1,200 rpm), shifting fire volume down to the squad level. Soviets and Americans answered with mass production of cheap submachine guns: PPSh-41 (over 6 million produced), Thompson, M3 'Grease Gun'.

In 1943–44 Germany introduced the Sturmgewehr 44, the first rifle using an intermediate cartridge (7.92×33 Kurz) with selective fire — the conceptual ancestor of the AK-47 and every modern assault rifle. The Allies ended the war still using semi-auto (M1 Garand) and bolt-action rifles (Lee-Enfield, Mosin), but the intermediate-caliber paradigm was already written.

Doctrinal legacy

Three revolutions: the general-purpose machine gun, the mass-issued SMG, the intermediate-caliber assault rifle. All three still define infantry armament today.
