The Grenadier is an individual equipped with a grenade launcher, either underbarreled or stand-alone.
His role is one similar to the rifleman with the added enhanced capability to engage Light Vehicles, larger groups of Infantry, or hostile Structures such as Fortifications.
The versatility of the 40mm grenades also allows the Grenadier to provide his Fireteam with further support such as providing smoke marking and concealment, flare illumination, or HuntIR recon.
The Grenadier is a more dedicated role than the Rifleman, since his loadout weight is increased because of the added 40mm grenades.
The primary weapon of the Grenadier is either an assault rifle with an attached UGL such as a M4 or M4A1 with a M203 or M320, or a AKM or AK-74 with an attached GP-25 or GP-30, or a standalone GL such a M320.
