The M91/30 is a weapon featured in Battlefield Vietnam, issued uniquely to the Viet CongScout kit. It features a 6x scope meant for long-range engagements. It is a generally a very powerful rifle, being capable of killing in 2 body shots or in a single head shot.
It is also very accurate, being highly capable of shooting a target that is over 200 meters away. When it comes to close quarters situations, the small cross hairs can be very effective for no-scoping shots, but it is still recommended to switch to a pistol due to the possibility of a missed shot. It can somewhat be considered an equivalent to the AmericanM40.
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.
