The UNSC-issued M9 High-Explosive Dual-Purpose Grenade (abbreviated M9 HE-DP Grenade), also known as the Fragmentation Grenade, Frag Grenade, or simply Nade to a large amount of players, functions in a manner very similar to contemporary hand grenades. When thrown, a blast bursts the grenade's shell open and sends many small metal fragments flying at high speed, causing damage to Energy shields, armor, and flesh in a nine meter (30ft) radius. Four of these grenades may be carried at a time. It is a good grenade for clearing rooms as it does not stick to walls.

Description

HE-DP stands for High-Explosive Dual-Purpose. This designation means that it is designed to be effective against infantry, soft-skinned, and lightly armored vehicles.

The grenade has a hard metal casing that is smooth. AP FRAG can be viewed on the M9's olive casing. AP designates "anti-personnel", indicating the weapon's intended use. The grenade must first hit the ground before exploding. In the grenade would not detonate mid-air.

The spoon is a device that is gripped while the grenade is being primed, and ensures it will not explode until after the spoon is released, as it starts the fuse of a grenade as it flies through the air after it is thrown. It is unknown how the M9 is first primed. The grenade has a button on its body. This would most likely be pushed to prime the M9 before tossing it.
