An insanely accurate belt-fed machine gun that uses the .50 BMG round, the M2HB is the heavy-barrel (to reduce cooling problems) successor to the original M2 machine gun.
1. An M2 fitted with a custom sniping scope held a record for longest-range confirmed kill until 2002.

2. I thought that escaping the MLRS's field of fire would be enough, until I felt the searing hot barrel of an M2 poking me in the leg.
