In the famous "tank missile" scene in Iron Man, the titular character is fired upon by an armored vehicle while engaging in vigilantism in the Middle East. In response, he fires a missile that annihilates the tank, presumably killing its occupants.
Upon a close look at the scene however, the trapezoidal turret and low sideskirts of the tank in question...
...resemble those of a NATO vehicle such as the;
American M1 Abrams
British Challenger II
And certainly don't resemble the Russian-made T-72, which insurgents would be far more likely to operate.
Is any reference ever made in or out of universe to whose tank that actually was? And is it ever determined whether Iron Man killed the insurgents he was after, or an American crew?
