Airburst round

From Wikipedia, the free encyclopedia

An airburst round is a bullet that detonates in midair, causing shrapnel damage to an enemy. This makes it easy to hit enemy soldiers behind a wall, in a foxhole,or in a confined space or room. It is used on many guns including the XM 29 assult rifle. It is like a grenade bullet. On many guns like the xm29, it is 20mm and is similar to a smart grenade. Although useful in many situations, it is not as effective as a hand or launcher grenade and it's fragments are not as dangerous but it is still a very dangerous weapon. To fire it you just set the distance you want it to detonate, fire, and watch the round explode in mid-air.
