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. However, some marksman rifles, like the M14 Mod 0 Enhanced and M39 EMR were derived from the M14 platform and still see usage in the modern day.
The M14 is issued to the American and South VietnameseEngineer 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.
Because Battlefield Vietnam features different loadouts for each faction, this list may not be specific enough. Please see each faction's respective page for information on individual weapon kits and loadouts.

— In-game description
In Battlefield: Bad Company 2: Vietnam, the M14 is 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 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.
