In Battlefield Vietnam, the Blowtorch is issued as an option to the Engineer kit of any American and South Vietnamese faction. The blowtorch is the opposite of the wrench, as the blowtorch inflicts damage to vehicles rather than renew its health. It is dangerous to use to destroy a vehicle, such as a tank, as the target will explode. It is recommended to only use the blowtorch to almost destroy a vehicle, and then finish it off with C4, which is also issued to the Engineer.
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.
In Battlefield 2: Modern Combat, the blowtorch is issued to the Engineer kit and acts as a repair tool. It differs from typical repair tools of the series in that it requires ammo (fuel) to function, and must be resupplied from an ammo crate or a new Engineer kit eventually if it used enough in a single life.
In Battlefield Heroes, the Blowtorch is an Soldier weapon used to melt tank steel. It has a very high rate of fire and damage, but a very limited range. It can be used to hurt infantry as well, but the victim needs to stand still not to miss him.
"Portable welding tool for emergency repairs. Caution! Keep away from burning flame."
