What is "ampulomet"

The Ampulomet (, also rendered Ampulomyot, ampulla mortar, etc., lit. "ampule/vial thrower" cf. миномёт) was an expedient anti-tank weapon which launched a 125mm 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.

The weapon weighed approximately 28 kg, and fired a 1.5 kg projectile up to 250m, at a rate of 8 rounds per minute with a crew of 3.
