In Battlefield Vietnam, the US and ARVNScout classes come equipped with yellow smoke grenades. A smoke grenade is deployed like a grenade, but is non-lethal and creates a relatively large plume of smoke where it lands. It is of no use in Singleplayer or Co-op, as it is completely ignored by AI soldiers. In Multiplayer, it can offer a limited screening effect or can be used as a distraction. If a team is well coordinated, it can serve as a marker for air support.
Each Scout equipped with smoke grenades is issued a total of 3.
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.
