Gunner Incendiary

Battlefield 4
Gunner Incendiary is a secondary weapon available for IFV and MBT gunners in Battlefield 4. Like Proximity Defense for mobile artillery in Battlefield 3, it provides close quarters defense.

After selecting the weapon, a single M34 Incendiary grenade is lobbed, exploding in mid-air, very close to the vehicle.

Currently, no indication is given of the weapon's availability when entering a vehicle, other than ammo count in the gunner's HUD.
