ok you know what Im just not going to come here anymore I dont need some persons opinion on the fucken best tank in the world .O and a 1963 corvette could smoke any crapy japenese car any day Ever considered speaking with a doctor With this kind of behaviour its better that you don't come here naymore as you said yourself. And the hull of the M1A1 and M1A2 is the same. What's your point? Besides additional NBC protection, the hull is the same on the M1A2. Keep in mind, the Challenger made the same upgrade, as well as updating it's armor protection. My point is that the Challenger 2 turret is a completely new design... You doubt it? That it? That's your response, your flawless presentation of facts to counter my point? That's a joke. You counter with something like "I doubt it" and expect me to take you seriously? I've searched google for some facts, and the first link a visited I read this: ''For the M1A2 Upgrade Program, over 600 M1 Abrams tanks are being upgraded to M1A2 configuration. Deliveries began in 1998.'' ''The US Army planned to procure a total of 1150 M1A2 SEP tanks but the US Army has decided to cancel future production of the M1A2 SEP from FY2004.'' Its from army technology. This kinds proves what I already thought. http://www.globalsecurity.org is the only redily available one I will even bother to show you. You'll notice that the Unites States keeps upgrading more and more Abrams to the M1A2 Standard. I don't really call this website reliable, about that ''first to fight units'' I think thats crap, very armored unit that goes to Iraq returns after 6 monds, than another unit is sended to Iraq, first to fight sounds like BS. And whats the big difference between te M1a1 and M1a2??? Only big difference that I can see s that the a2 has a thermal sight for the commander, they have installed things like APU's and such on the M1a1 also.
