Complete the Rocket Specialist assignment
— Battlelog Description
Air-Burst Missiles are available for use by Mobile Artillery vehicles, unlocked via the Rocket Specialist assignment. The secondary armament is swapped out for two air-burst missiles, with a reload time of five seconds. The missiles otherwise have the same properties as the standard rockets, but have no splash indicator. They have a 4-5 meters of radius mortal area, which instantly kills everyone in the area. They possess a bigger explosion than the standard rockets.
As implied by the Battlelog description, these missiles are less effective against armor or structures. A quirk of the weapon—due to game design—is that it must actually impact a surface, after which an airburst will occur slightly behind.
