Special: Fragment Damage ammo explodes into fragments on impact with anything, creating "fragments" that deal 10% of the damage of the gun each (the number of fragments being dependent on the gun, and each dealing the same damage). The fragments go in random directions from the point of impact up to twice the size of the AoE of the gun. As such, while the gun with this damage type may not hurt your ally, if you miss but hit your ally, the gun can still hit the enemy if they are close enough.
