The Breda 38 received the German identification code Kampfwagen-Maschinengewehr 350(i).

[2] For this purpose the gun was mounted on a machine-gun tripod by means of an adapter, and was fitted with a temporary rear sight on the right of the body and a temporary front sight on the right of the barrel at the muzzle.

The gun is air-cooled, gas-operated, and magazine-fed, and has a quick-change barrel.

Its operational features are simple, and it is extremely easy to field-strip or disassemble completely.

The barrel is sufficiently heavy (4,5 kg) to enable it to fire a large number of rounds in quick succession without overheating.
