The Knife is an all kit weapon featured in Battlefield Vietnam. The knife retains the same statistics as the Battlefield 1942 variant but features a drastically different design, being much larger, and held with the blade down and to the side, rather than upright. The Axis knife was also redesigned into the Machete.
The files for the ARVN and US military knives are the same as those used by the allies' knife in Battlefield 1942, with a different model. The axis combat knife still exists in the game files, but goes unused, replaced by the NVA and Viet Cong melee weapons.
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.
