Cobra Island Control Tower
"This imposing control tower dominates the small rugged airfield on Cobra Island. With its serpentine sculptures and thick sloped walls that effectively turn it into a sturdy bunker, the Control Tower represents the classic Cobra style of architecture.
Intelligence reports indicate that at least a dozen Cobra troops can be found in or around the tower at any given time. Any assault on this strong point would be a risky proposition and very costly in lives, unless the garrison could somehow be taken by surprise. But in the event of any attempt to take the airfield, occupying the Control Tower will be vital to success..."
The Cobra Island Civil War is probably my favorite of all the big story arcs from the original GIJoe comic. A lot of the action took place around the Cobra Island Airfield, where command of the Control Tower was essential.
