My thoughts (as a Challenger 2 Commander) is that he should go. He wants to and it should be allowed. Anybody who thinks the insurgents are just going to stop targeting CVRT's because he isn't going would be wrong.
To these people we are the infidels and we must be lying about him not going.
Plans will already be set and they will just pick a random troop to attack.
I thank god I have a Challenger 2 and not a CVRT. That said one of my boys lost a leg a few weeks back when they attempted to destroy the wagon he was driving.
Currently being repaired

the tank not his leg
