The M14 is an American selective-fire battle rifle derived from the M1 Garand. It fires 7.62x51mm NATO cartridges. It was the standard issue rifle for the U.S. Armed forces from 1957, replacing the M1 Garand, to 1970, being replaced by the M16. It was used extensively during the Vietnam era, but was phased out very quickly during and after that conflict.
Post-Vietnam, some marksman rifles, like the Mk. 14 EBR and M39 EMR were derived from the M14 platform and still see usage in the modern day. The Springfield Armory M1A SOCOM 16 is a civilian derivative of the M14. The SRSS Bulldog is a civilian bullpup chassis for the M14.
The M14 is a weapon featured in Battlefield Vietnam, is issued to the American and South Vietnamese Engineer kits and is an option for the Heavy Assault kit. It can kill in 2-3 body shots or a single head shot. It has high accuracy moderate speed, and a medium reload time.
Battlefield: Bad Company 2: VietnamEdit
— In-game description
The M14 is a weapon featured in the Battlefield: Bad Company 2: Vietnam expansion, issued to the Assault kit. It has a 20-round magazine and a fully-automatic fire mode. It has the lowest rate of fire of the assault rifles, but this is balanced by the highest damage and fastest reload time.
It also has the lowest accuracy, the largest hipfire spread, and the highest recoil, limiting the user to fire in bursts at mid-long range to maintain accuracy. Its sights are very similar to those of the M1 Garand from the base game. It is comparable to the G3 in the base game, as it has high damage, low rate of fire, high but controllable recoil, and a small, 20-round magazine.
