The LAD machine gun (Russian: пулемет ЛАД Pulemyot LAD) is a Soviet prototype heavy submachine gun. Although belt-fed and having a built-in bipod, it is chambered for the Tokarev pistol cartridge.
The LAD was developed between 1942-1943 by Vasily Lyuty, Nikolay Afanasyev, and Vladimir Deykin; the "LAD" designation is a contraction of all three of their names. Only two prototypes were built and it was not accepted for service.
The two examples are currently found at the Saint Petersburg Artillery Museum.
