XM510 grenade launcher

The XM510 Multishot Grenade Launcher is a semi-automatic grenade launcher used by the UNSC Marine Corps. In Halo Wars, the Grenadier upgrade for the Warthog adds a Marine equipped with an XM510 in the passenger seat to improve attack strength of the vehicle.

Trivia
The Halo Wars: Official Strategy Guide once mistakenly refers to the "XM511" as the "XM510" in a caption describing the weapon mounted on the Wolverine.
