The UNSC M9 high-explosive, dual-purpose grenade is a thrown fragmentation device. Use it to suppress or disable vehicles, except tanks. It can be thrown, rolled, bounced or ricocheted into places direct fire weapons can't reach. Increase the angle of the throw to toss it farther, or to get it over obstacles. Be careful not to throw it too close to your own location.
