Panzerfaust M60 "Tank Fist"
The Panzerfaust was a very successful disposable anti-tank weapon.
Developed by HASAG Hugo Schneider AG, Werk Schlieben, the first of three models (M30) was issued in August 1943. Shown here is the second variant, the M60, adopted in August 1944. The final version, M100 was fielded in November 1944
The M60 designation was derived from its optimal effective range of 60 meters (200 ft.).

The Panzerfaust was an improvement over the Panzerschrek rocket launcher in that it was easy to produce, light and was operated by one person requiring almost no training. It was issued in an assembled condition and was a single shot disposable weapon. (However, fired tubes were often recycled and reloaded at the factory.)
Well over one million were produced before the end of the war.

Operation
This very simple and effective weapon operated on the action-reaction principal . Inside the launch tube was a small black powder charge. When fired, the finned bomb moved forward due to the force of the expanding gas. Since the momentum of the warhead was created by reaction to the mass of the high velocity gas exiting out the tube, there was no recoil.
The Panzerfaust was not a rocket launcher, but rather a smooth bore recoilless rifle.
