"The Grenadier is the ultimate expression of controlled aggression on the battlefield. It is this soldier’s job to quickly and efficiently incapacitate, through whatever available means, any attacking hostiles. Lacking any attacking targets, any hostiles at all will do.
Grenadiers are the most aggressively offensive troops of the Soldier career path. AFS troops that master Grenadier training use many types of heavy weaponry, including deadly propellant guns that lay waste to Bane forces. Heavy armor and high health are necessary to any Grenadier."
