3M6 Shmel

Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Tungsten alloy swaging rod is widely used in industry as well as military areas, such as rifle bullet, armor piercing, snipe rifle penetrator, etc. Tungsten alloy swaging rod is used for 3M6 Shmel.

The 3M6 Shmel is an MCLOS wire-guided Anti-tank missile of the Soviet Union. "3M6" is its GRAU designation. Its NATO reporting name is AT-1 Snapper.

Too large to be manportable, it was typically deployed from specialised vehicles or helicopters. The missile was intended to supplement traditional anti-tank weapons like the 100 mm anti-tank gun whose accuracy beyond 1500 m is poor. The missiles' accuracy in contrast remained high as far as its maximum range of 2000 m.

However the system's bulk, slow speed and poor combat accuracy drove development of later SACLOS systems like the AT-5 Spandrel.
