MARINES TESTING A BATTALION ARMED WITH SILENCER-EQUIPPED WEAPONS: During the tests every “element” of 1st Battalion 2nd Marines will utilize silencer-equipped weapons, from M-4s to .50 caliber heavy machine guns.

They’ve already done some experimentation.

“What we’ve found so far is it revolutionizes the way we fight,” Love told Military.com. “It used to be a squad would be dispersed out over maybe 100 yards, so the squad leader couldn’t really communicate with the members at the far end because of all the noise of the weapons. Now they can actually just communicate, and be able to command and control and effectively direct those fires.”

Suppressors work by slowing the escape of propellant gases when a gun is fired, which drastically reduces the sound signature. Used by scout snipers and special operations troops to preserve their stealth, the devices are also valuable for their ability to minimize the chaos of battle, enabling not only better communication but also improved situational awareness and accuracy.

Good. FWIW I recall a couple of late night discussions in the 1970s –lieutenants and captains ruminating while sipping beverages– where arming infantry companies and battalions with silenced weapons was a subject of professional speculation.
