nowadays the yanks have aircraft which can map out every single armoured vehicle in theatre in about twenty seconds, if won't be too long before some bright spark makes the B-1s carry homing missiles, so as far as i can see the enemie's armour will be destroyed in the first day of any future war with america.
and if there is no enemy armour there is precious little need to bring armour of our own. even if you can think of a reasonable reason to bring a challenger it is a massive logisitcal head ache (the main limiting factor for the american advance of the Gulf Wars was the fact their armour kept on out running its own fuel) as well as that you have countless blokes running around not well pacifified areas trying to keep it supplied.
there is nothing armour can do which air power can't do quicker, better, more accurately and safer.
(oh and before anyone says it, if you don't have air superiority your going to die. all your shiney armour vehicles (or boats) will be are targets, e.g. the falklands, gulf 1, and gulf 2)
modern Anti-Air is NOT controlled manually, it's controlled by a computer and radar because it's impossible to hide when you're always out in the open, radars can spor Air Units from over 10 Miles away and that's just the small ones mounted on tanks, you think air units can blow anything apart from a safe height? and you also believe we wouldn't make a way to counter them?
a single round from that rapid fire cannon can rip a hole in an aircraft and at those speed that single hole will rip a wing off. and by the way, Fighter Planes cannot fly between continents, they need airports and aircraft-carriers to follow them where ever they go. aircraft-carriers are also often equiped with plenty of anti-air with huge radars to back up the defense
did I forget to mention that missiles can be blown out of the sky with this same technology?
