Devil's Due Comics is doing a good storyline on the Cobra Special Forces.

Plague Troopers are individuals from various troops (Sand Vipers, Saw Vipers, Eels, etc) that have set themselves apart from their peers and so a special force The Plague has been created which is made up of these special troopers.
