The M72 rifle is of German design. It uses an electromagnetic field to propel 2mm steel rounds at tremendous speed... and pierce almost any obstacle. Its range, accuracy and stopping power is almost unparalleled.
The Gauss rifle, also called a coil gun, is a device used to propel a ferromagnetic projectile by accelerating it through a process of magnet induction. The Gauss rifle (and Gauss gun) are named after German mathematician Carl Friedrich Gauss, who formulated mathematical descriptions of the magnetic effect demonstrated by magnetic accelerators.
