I saw a program on pay tv last night dealing with how the yanks deal with their old abrams and I have gotta say I was impressed. They haven't built a new tank since 1993. What is the situation with the Brits in relation to old tanks? Do you do the same. I realise the Challenger 2 is quite new, but would you rebuild or recondition? On a personal note I believe the Australlian Army bought the wrong MBT and should have gone for the Challenger 2. My humble opinion. Would love some feedback... remember fellas I am a ground dweller and really have no knowledge of MBT's, so be gentle. What is the considered opinion,(bias aside), of the M1A1 v Challenger 2?
