PKM

The PKM is a Russian 7.62mm General Purpose Machine Gun designed in the Soviet Union and currently in production in Russia. The PK machine gun was introduced in the 1960s and replaced the SGM and RPD machine guns in the Soviet arsenal. The PK machine gun can be used as a light Anti-Aircraft weapon when it is put on an AA mount, as it's big 7.62x54mm cartridge is capable of inflicting enough damage to aircraft. One feature typical of Soviet Machine Guns is that the standard model feeds from the right and ejects its spent cases via an ejection port on the left side of the weapon, as opposed to the right side ejection port seen in most Western Machine Guns such as the M249 SAW.

The PKM Appears in Battlefield 2, Battlefield: Bad Company and Battlefield: Bad Company 2

Battlefield 2
The  PKM  is the Tier 1 unlock for the Support class in Battlefield 2. It is both more powerful and more accurate than the other support weapons, and is one of the two weapons most commonly employed in "Dolphin Diving" (the other being the M95).

Battlefield: Bad Company
The  PKM  is the main general purpose Machine Gun for the Russian Armed Forces' Support kit. The American counterpart of the gun is the M249 SAW.

The PKM has 150 bullets and the player will have 300 in reserve. It has a good rate of fire and medium damage, but its performance is doused by low accuracy.

Battlefield: Bad Company 2
The PKM LMG is the default weapons for medics in Battlefield: Bad Company 2. The gun reduces the player's movement and has medium power and recoil. For a starting weapon, the PKM is surprisingly effective having both considerable damage and high accuracy, even during prolonged bursts. While moving, however, the weapon sways significantly making kills on the move nearly impossible. Its main drawback is the slow rate of fire and sway while moving, a common disadvantage for LMGs, which makes it inferior to most assault rifles. The addition of wide crosshairs and terrible accuracy when hip firing also place it below most other guns at close range. Although it has moderate stats in all categories, the PKM does not surpass other weapons in any one role.
