Fire Extinguisher

A fire extinguisher is an active fire protection device used to extinguish or control small fires, using an extinguishing agent. Small vehicles may carry extinguishing systems to protect engines and fuel stores from flame.

Battlefield 3
A specialization available for air vehicles, the Extinguisher will put out engine fires and return the disabled vehicle to 37% health, sufficient to prevent further health loss and possibly regenerate the remaining health. After use it takes 25 seconds to recharge.

This specialisation greatly helps aircraft as it can prevent the aircraft from being destroyed which would handicap that team and give the enemy team a chance to gain air superiority. Aircraft are also difficult to repair as they must land first; this is harder with jets compared to helicopters.

Extinguisher coupled with Maintenance gives the player's aircraft greater survivability, as the Extinguisher can allow the aircraft to regenerated health after being disabled and Maintenance can regenerate the aircraft's health to full at a greater speed than normal.
