CCT is still amazing. Go watch Tyms vet 3 cct + firefly. God knows how Tym gets all those vet 3 ccts, but they make his vehicles real punishers.
They also make the 95mm cromwell ridicolous.
Another allied perk.
Keep it alive? I'm trying to get a second like i used to have but it keeps dying, so meh. I think i should put flank speed on it. smoke helps too. the creeping smoke barrage is excellent and i'm the only person i ever see use it.
No secret to getting a vet 3 cct, just use a priest and its there in about 2-3 games.
I dont have a priest and i've had my vet 3 cct for a looong time. I generally use stags, and firefly's, mainly fireflies, to vet 'em up, no secrets, just keep it alive.
Heck, i dont even have the highest cct, that belongs to Panda and he's 2nd on the brit leaderboard with it.
