Ampulomet [SEP] service entry
Ampulomet
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.
Design.
 The weapon consisted of an unrifled tube with a crude breach mounted on
of manufacture and low maintenance requirements. It was, as one Home Guard volunteer put it, "something to be accepted gratefully until something better arrived." 
Like many of the obsolete weapons designed for the Home Guard, the Northover Projector was only taken out of service when it could be replaced with "marginally less ineffective" weapons provided by the Army, such as the 2-pounder anti-tank gun.
