Frag Grenades are throwable weapons in Devil's Third.
A standard hand grenade. An anti-personnel throwable weapon that is designed to give damage to people nearby with its time delayed fragmentation. Its time delay is roughly 4.5 seconds. It can be readied and held in hand longer, so it explodes quicker after it is thrown. However it is possible to hold the grenade so long that it explodes while still being held. It cannot damage built structure modules or obstacles during sieges.
