The Flame Grenadier was a Locust Grenadier armed exclusively with the Scorcher Flamethrower, and, like all grenadier classes, specialized in CQC. They were first encountered during the Destruction of Halvo Bay, though only as prototypes to test their capabilities, and later on the Coalition encountered more armored Grenadiers during the Evacuation of Ilima, and later Operation: Hollow Storm. Flame Grenadiers are also equipped with a backpack fuel tank that significantly increases the fuel capacity of the Scorcher.
