GI Joe issue #8 was one of my favourites way back in the day. At the time, Cobra had a paucity of vehicles to use against the Joes, so the creative team went all-out in that issue in creating equipment for the bad guys. They had an undersea base, a boat/submarine called the SRV-9 (Submersible Reconnaissance Vessel Mark 9), attack walkers called SEA Legs (Surprise, Engage and Attack) and finally tracked cannons called Amphibious Assault Guns. This custom is inspired by the AAG (an abbreviation not actually used in the comic), though not really based on it because it's at a smaller scale. The comic AAGs were the size of tanks, while my custom is smaller and operated by a single soldier. The operator is a custom Cobra Marine.
