Members of the 9th Pyro-Marines are elite advance boarders they use minimum manpower and maximum firepower to gain a foothold in the enemy vessel. Equipped with Mk XII flamethrowers. The Pyro-Marines carry their own oxygen both to fuel their infernos and to breathe when the air in the ship is depleted. Additionally the tanks carrying their dangerous cargo are armored against COP small arms. But in the event of a premature detonation their body armor is made with fire retardant polymers and refrigeration systems to protect themselves. The Mk. XII deploys a type of jelly gasoline similar to napalm but burning at a much higher temperature adhering to both man and machine.
