The M60 machine gun has its roots in the BAR of World War II. 
Designed to give the infantry man the power of a heavy machine
gun, the firearm fires a 7.62mm round and uses the ammo in the 
form of belts.  This weapon was not designed to be fired from
a standing position and is most useful and more accurate if
placed on a solid object such as the ground while prone.
