In Battlefield Vietnam, the M16 is one of the standard issue assault rifles for the American and South Vietnamese factions. It is issued to the Assault kit. It is functionally similar to the CAR-15. It has medium damage, medium recoil, average spread and a high rate of fire. It can kill in up to four-five shots. In close-quarters, it can be very effective due to its high power. It is limited by a small 20 round magazine and a relatively long reload.
The M16 Sniper is also available for all American and South Vietnamese divisions. It is issued to the Scout kit. Like stated in its name, it is essentially an M16 with a x6 zoom scope, meant for medium range engagements. It holds the same characteristics of the regular M16, only being limited to semi-automatic fire. It should be noted that it still has the same accuracy, meaning that outside of medium range its spread can throw off one's aim. The user of this rifle will also only have two spare magazines instead of the normal six of its non-scoped counterpart.
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.
