Ampulomet Model 1941
The Ampulomet is a 125mm grenade launcher introduced in 1941-42 to give the infantry a weapon to fight tanks. It uses a special 12 gauge shotgun cartridge to launch a FBM-125 anti-tank grenade easily capable of penetrating the thickest armor that enemy can throw.
A black powder charge was inserted into the breech and fired by a percussion cap to propel the AZh-2 glass ampule.
The ampules were filled with an incendiary mixture known as KS.
KS was a mixture of 80% phosphorus and 20% sulfur which ignited when exposed to air.
The burning mixture created a bright flame, thick white smoke and would burn for up to three minutes at temperatures between 800–1,000 °C.
The burning liquid would seep through vision slots or engine grilles on a tank and ignite ammunition or fuel as well as choke and killing the crew.
