Incendiary grenades

incendiary weapon using flammable liquid in a bottle

The Ampulomet (, also rendered Ampulomyot, ampulla mortar, etc., lit. "ampule/vial thrower" cf. миномёт) was an expedient anti-tank weapon which launched a 125 mm incendiary projectile made of spherical glass. This weapon was introduced in 1941 and used (to a limited degree) by the Red Army in World War II, but by 1942 was largely obsolete.
