U.S. Marines assigned to 2d Low Altitude Air Defense Battalion (LAAD) and Headquarters Battery, 10th Marine Regiment participate in a heavy machine gun range training day, where they used .50 cal machine gun and M240 against old tanks.

The M240 has been used by the United States since the mid-1980s and is used by infantry, armored or not, boats and aircraft; although not the MMG (medium machine gun) lighter in service, the M240 is widely seen as a highly effective and reliable weapon, and its standardization among NATO forces was seen as a great advantage.
