The Standard Issue Assault Anti-personnel Fragmentation Grenade, or commonly the Frag Grenade, is Pyroneous Industries cheapest, lightest and most explosive fragmentation grenade. It is used by standard battlefield operatives from the Covenant Pirates and Jiralhanae Alliance. It has a 25 metre blast radius and an effective lethal radius of 5 metres. It is useful for close combat infiltration, as it can ‘bounce’ off of surfaces and around corners. This is the perfect urban assault infiltrator but isn’t that stealthy.
