M9 fragmentation grenade

The UNSC-issued standard fragmentation grenade functions in a manner very similar to contemporary hand grenades. Though fragmentation grenades lack shrapnel, their concussion is powerful against both shielded and unshielded enemies. Only four may be carried at a time. An "infinite grenades" option is available in multiplayer on a single Xbox, as well as in all multiplayer Halo PC games.

Advantages
This grenade can be bounced around corners and travels farther than the Plasma grenade. It is also harder to see and has a shorter fuse, therefore making it harder to avoid and more useful for killing enemies on foot.

Disadvantages
Unlike the Plasma grenade, this grenade doesn't stick to objects, making it harder to hit vehicles. Since it is harder to see, running over one by accident can happen more easily than with a luminescent plasma grenade.

Multiplayer Tactics


A multipurpose weapon, the fragmentation grenade can be used in corridors to flush out occupants. If lobbed under a vehicle, the explosion will either kill or severely injure the occupants. If timed correctly, grenades can be planted in the path of an oncoming vehicle. Most drivers will not be able to react quickly enough, and will most likely be caught in the blast.

Effective Against
Anything Land Based.
