I’ve posted about the M-32 40mm grenade launcher, the MGL-140 by Milkor, several times over the past few years.
Here’s the latest: Use of multishot grenade launchers to grow
Prompted by its success in defending against convoy attacks and ambushes, the Corps will vastly expand the availability of a 40mm, six-shot rotational grenade launcher first fielded in Iraq on an experimental basis in 2006.
For the first time, the launchers will be fielded “across the board,” said Patrick Cantwell, a former captain who now works as the Corps’ small arms capability integration officer. The weapons will be assigned to headquarters units and distributed upon the request of individual unit commanders, going to everyone from military police to infantry and logistics units.
The Marines are planning to purchase over 2,100 of the units, but there will be an open competition. I’ve heard nothing but good things about the M-32s already in use.
