GF MarineEditFederation Marines are members of the Galactic Federation Marine Corps, who wear advanced powered armorsuits. These suits allow them to use potent weapons and resist heavy damage in battle;few can match them in combat. One of the most common sights on Federation worlds, the Marines are the rank-and-file soldiers of the Galactic Federation.
Demolition Troopers are members of the Galactic Federation who are outfitted with explosive weaponry for special missions. While capable of destroying the strongest of barriers, they are very good at combat. When the only way to the objective is straight through an obstructing object, Demolition Troopers are called upon to make it happen. They seem to have weaker versions of the Galactic Federation Marine's assault rifles. Their explosives are carried on their back.
Federation "PED Marines" were Federation Marines of the Galactic Federation with a Phazon Enhancement Device attached to their suit. Only elite troops were allowed to use the devices. With the attachment of the PED, PED Marines could utilize Phazon to increase the power of their armor. While active, the "PED" enhanced the attack and defense systems of their suits.
