MM-1 grenade launcher had been made fairly popular by movies and computer games. However, it`s pretty formidable weapon on its own.

Featuring a 12 round drum, and semi-automatic action, MM-1 can offer a very significant amount of firepower in short time. Even though it`s relative rate of fire is certainly not machinegun-like, it can empty its whole drum in under half-minute. Considering that it fires standard issue 40 x 46mm grenades, this is pretty much close enough to fully automatic.

Among the problems of MM-1 the most notable would be problem of reloading. To perform reload, one has to disconnect the rear part of the gun, and swivel it up, exposing the drum, which is fixed, and replace the rounds one-by-one. Additionally, spring has to be wound up to allow for drum revolving.

This gun is probably connected to Manville gas guns, which used similar ways of working. Also, MM-1 is quite similar to South African Milkor MGL and Russian RG-6.
