The Army is developing new 40mm training rounds for both individual grenade launchers and crew-served weapons that will allow for “more realistic” training than those currently in use, Military Times reports.
According to officials, the training rounds being used now are too volatile for firing into areas where dismounted troops are about the pass through. In combat, soldiers will often initiate an assault by shooting 40mm rounds at their objective, which means the current training rounds limit a unit’s ability to train how it fights.
“Typically, soldiers can’t conduct fire and maneuver training due to the safety risk,” Christopher Seacord, product director for medium caliber ammunition, told Military Times. “What we would like to do is remove the energetic from the cartridge so that even if it did not function downrange, and someone stepped on it or picked it up, it would not hurt them.”
The Army is redesigning two types of 40mm training rounds: low velocity, or LV, and high velocity, or HV. LV rounds are used with individual weapons, like the M320 and M203 grenade launchers, while HV rounds are used with crew-served weapons, such as the Mk19 Grenade Machine Gun, all of which have seen extensive action on the battlefields of Iraq and Afghanistan.
The new training rounds have already entered initial production but require more testing. As Military Times reports, the LV round will be produced by General Dynamics and the HV round will be produced by American Ordnance. The capsules are filled with a more stable material than the energetics that fill the rounds currently being used, and will not contain fuses.
With only 10 components, the new HV design is far less complicated than its predecessor, comprised of 39 parts. It’s also cheaper, expected to save the Army $4 per round or, as Military Times reports, approximately $8 million for the service’s total ammunition stock. The goal is to have both rounds fielded by August 2019.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.

In the six months since its activation, the Navy's 2nd Fleet has bulked up and is embracing its mission in the North Atlantic and the Arctic, where the U.S. and its partners are focused on countering a sophisticated and wily Russian navy.
