I've decided that Cobra Commander just creates new troop types on a whim. Or his underlings do, and he approves.

I used to follow the file cards. But early on they made Cobra Officers, Stinger and Hiss drivers O-4's! What the heck? A jeep driver is a Major? A 2-man tank operator is, too?

The blue shirt and Viper thing isn't hard for me.

Now, CLAWS, HEAT Viper and Fast Blast Vipers get odd. Now there's a Bazooka Trooper coming...meaning blue shirts have weps "specialists", too.

Frogmen: Eels, Hydro Vipers, Morays and Undertows...too many divers

Flamethrowers: Incinerators, Shock Vipers, and there's a desert Cobra trooper flamethrower coming. A lot for a limited use weapon.

Ninjas...so many, I chalk most up to being mercs, except Ninja Troopers/Vipers who are trained Cobras.
