Quite possibly. 2d MarDiv is looking at just that, even as we speak:
Maj. Gen. John Love of 2nd Marine Division out of Camp Lejeune, North Carolina, is gathering data on the way suppressors improve battlefield communication and efficiency. Early testing at Marine Corps Air-Ground Combat Center Twentynine Palms indicates that suppressing everything from M4 rifles to .50 caliber machine guns can dramatically assist U.S. warfighters.
The price tag for each battalion is said to be $700k. That’s a lot of money, especially in today’s fiscally challenged environment, as the phrase goes. Also, who wants to add more serialized gear? And there are maintenance issues too– somebody better informed should correct me, but aren’t “cans” really hard on guns?
This venture has some distinct prospects, but I’ll be interested to see if the Commandant thinks the benefits outweigh the costs.
