Not sure if it could be considered as corp, but either Republic Commandos or Rancor Battalion

^Maybe the Special Operations Brigade?

The Bad Batch (Hunter, Tech, Crosshair, Wrecker, Echo and Omega)

^Thats a squad, not an army corps.

Wolf Pack

^ay same brother!

Probable the 104th. Or if we are talking clone units in general no matter the size than most likely Delta Squad.

@Natsuki151 Putting aside the fact Corps isn't spelled right then (It is in fact spelled Corps with an s because English is a dumb language and Corps is both singular and plural)

Anyway assuming you just meant unit in general (because there aren't that many Corps) well the 104th because Wolffe is great, but second is the 327th

@Red5T65 I'm aware that corps is spelled with an s at the end. I got rid of it cause I thought that someone had gotten it confused with another word. I added them back for you

I didn't watch clone wars
