The Mossberg 500 is a weapon featured in Battlefield Vietnam issued to the US Army and US Marine CorpsAssault kits as an alternative to the M16. It has a 6-round magazine tube, and fires buckshot shells with potential to kill instantly at very close ranges. After about 20 meters, more shots become necessary to bring a target down.
Also, while powerful, the Mossberg's pump action is time-consuming to cycle, making the rate of fire on the Mossberg very low. This makes follow-up shots necessary at longer ranges impractical. The shotgun is an excellent close-quarters weapon, but too specialized in that role to be useful for anything else
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.
