The M82 is an American Anti-Materiel heavy sniper rifle featured in Medal of Honor (2010). The M82 is developed by Barrett in the 1980s. The M82 fires the powerful .50 BMG (12.7x99mm NATO) ammunition, which was originally developed for and used in M2 Browning machine guns. It has an effective range of 1,800m (5,900 ft).
It is equipped with an electronic, variable-zoom scope, capable of thermal with both black and white-hot imagery. In Running with Wolves..., it has a suppressor equipped and can be seen on Deuce's ATV. In Friends from Afar, Deuce and Dusty use it to eliminate several enemy camps in the Helmand Valley that were threatening AFO Neptune.
- In Friends From Afar, the second and last mission in which the player uses the M82, it is possible to get the "Like a Surgeon" Achievement/Trophy with this sniper rifle since there are many enemies in the mountain across that haven't spotted the player at all.
- The weapon is actually M107, an improved version of the original M82 that was officially adopted by US army in 2002.
