A Wrench is a general purpose tool. The Wrench is generally used to repair many objects and can also be utilized as a weapon. Aside from that, the wrench is used as an identifying icon for kits that feature the Repair Tool in the Battlefield series.
The Wrench is a gadget issued to the Engineer Kit in Battlefield Vietnam. It functions similar to Battlefield 1942, having to cool down after a designated amount of time after repairing.
— In-game description
The HOFF-3 Wrench is issued to the Engineer kit in Battlefield 2. After a short animation, where the user widens the mouth of the wrench, the player can use it to repair friendly or neutral vehicles. It can also rebuild bridges which have been damaged or destroyed by C4 or other explosives.
The Wrench in Battlefield Heroes functions similar to bandages, restoring armor over a brief period of time. Only the driver of a vehicle may repair it. Wrenches also put out fires caused by Burning Bullets. Should the vehicle receive further damage, the repair effect is cancelled.
Each wrench has a limited number of uses, and must be purchased with Valor Points. Only one kind of wrench can be equipped at a time.
Battlefield 1943EditThe Wrench is a blunt weapon and vehicle repair tool in Battlefield 1943 for the USMC (M12 variant) and IJN (Type 12 variant) Infantry kits. Used against infantry, it is a one-hit kill, just like all melee weapons in the game.
In "Through Mud and Blood", the Repair Tool is collected by Daniel Edwards from Finch after he is killed in action. He can potentially trade the repair tool for other gadgets. Although this puts Black Bess in danger of being destroyed in combat, replacement tools can often be found in weapon crates.
As before, the repair tool allows players to repair friendly vehicles from outside, inflict damage to enemy vehicles, repair map placements, and attack enemy soldiers. Multiple players can repair the same vehicle more quickly, but at a reduced individual rate.
The repair tool grants tankers and pilots the ability to repair the vehicle they are operating from within, reminiscent of the wrench's function in Battlefield Heroes. Armor is regained in 20 point increments every five seconds for heavy armored ground vehicles, and in 25 point increments for air vehicles.
During internal repair, the vehicle cannot be operated by the player, leaving tracked ground vehicles stationary and air vehicles gliding. Wheeled vehicles may be driven forward or backward, but cannot be steered. Internal repair can be cancelled by enemy fire, or by the player performing any other action. Other vehicle occupants can continue to use other seats as normal.
Although internal repair is intended primarily for tankers and pilots, supports with a repair tool equipped and occupying the driver seat can also do internal repairs.
Modular damage to vehicles can only be repaired internally.
Although it can be used for attack, the repair tool deals little damage to vehicles and horses, and the player still carries a standard melee weapon for assailing infantry. Unlike dedicated melee weapons, the repair tool can inflict greater damage with headshots, and can kill targets without entering a takedown, but also without claiming dogtags. The user must land precise blows with the repair tool, as it lacks the wide hit area of melee weapons.
- During the Battlefield 1 beta, the repair tool could "repair" horses, as they are considered vehicles.
- This still appears to be possible in the released game when a teammate is riding the injured horse. Otherwise, the user will strike the horse, inflicting damage.
- In Battlefield 1 the repair tool was originally intended for the Medic class.
