An Airburst Grenade is a type of explosive ammunition that detonates in midair, causing an air burst effect, causing shrapnel damage to anyone in the grenade's radius. It is used in many weapons such as the XM25 and unlike traditional grenades, such as the 40mm Grenade, they can be electronically programmed to explode after traveling a certain distance.
The Airburst Grenade is a Tier 3 equipment expertise training option for the Engineer Class in Battlefield Play4Free. When taken, the player is granted the use of the XM-25 Grenade Launcher, which fires explosive projectiles that can be set to detonate at a specific range.
The 25mm Airburst Grenade is an explosive ammunition option for the XM25 launcher. Though its mechanics have yet to be fully revealed, it is expected to take ranging information (via ADS) from the launcher body, allowing the grenades to explode the same distance away. This would allow the weapon to indirectly attack enemies taking cover.
