I love elite armoured but those two abilities make me sad. While british tank commander gives +10 sight, +10% accuracy, +20 camouflage detection radius, +20% experience gained this one gives a whopping +6 vision and the worst arty in the game.
As for crit repait USF can do it instantly for 10 munis. Emergency repairs costs 50 munis and takes 14 seconds to repair a crit.
It is really wierd that doctrinal abilities are several time worse that stock abilities. Those two should be buffed to an acceptable level.
