This video is when U.S. Marines conduct training with M240B machine guns during exercise in Jordan.
According to Wikipedia, The M240—officially the Machine Gun, 7.62 mm, M240—is the U.S. military designation for the FN MAG, a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge.
The M240B and M240G are usually fired from integrated bipods, tripods, or vehicular mounts; regarding tripod use, the U.S. Army primarily uses the M192 lightweight ground mount, while the U.S. Marine Corps uses the M122A1 tripod, a slightly updated M2 tripod.
