I was never a big fan of the later army builders anyway. To me, Cobra is always going to made up of Cobra Troopers, Officers, Televipers, and Crimson Guard.
Oh, and Eels/Snow Serpants of course... And I would say the paraviper is insanely cool as well.
When they went onto all those other guys though (Vipers, Alley Vipers, Techno Vipers, Wiper Vipers, Pharmacist Vipers, Custodial Engineering Vipers, Teaching Certified Vipers, etc.), I really wasn't into all those. The earlier army guys were the best.
I think the Resolute Cobra Troopers are without a doubt far cooler than all those other guys Hasbro whipped up.
