Eels are the underwater demolitions specialists of the COBRA legions. They man and operate the COBRA marine outposts disguised as off-shore drilling rigs and augment the crews of larger COBRA naval vessels.
Eels undergo a rigorous two-part training program in the Caribbean and in the frigid dark depths of the North Atlantic. Their training regiment includes marine structural engineering, explosive ordnance, underwater fighting techniques and marine geology.

COBRA NIGHT WATCH troops are on duty during the dark, empty hours from midnight to dawn. While the rest of the COBRA infantry troops are dreaming of mortars and machine guns, night troopers patrol the perimeters and remain ready for a nighttime attack...which never comes, much to their disappointment. They drink gallons of super-caffeinated coffee to remain alert, haunted by nasty stories of what happens to anyone found asleep at his post by COBRA COMMANDER. Night troopers are ideally suited for their job. They shun the sunlight and skulk in the shadows even when not on duty. Because they are chronically sleep-deprived, they have learned the fine art of sleeping with one eye open so as always [to] be at least half-awake at all times.
"COBRA NIGHT WATCH troops are always wired from too much coffee and too little sleep. You don't want to startle them, because they're so jumpy that they attack first and ask questions later."
