Claudio is pretty awesome though - just make sure and keep a couple of support tokens on him if he does roll a zero. He will definitely take down a lot of 'stealers if played properly.
Sadly, you can have all 12 Support tokens on him, if the 'stealers attack from behind him, no using them. Nor can he reroll for his Heroic Charge. Personally, I'd load Sergeant Lorenzo with them, he can kill a whole swarm while defending when using the Support Action if you get lucky.
