@uugieboogie: The scene where he takes out Vallon's gang. He said to shoot with 50 cal.
Steve taking out the quinjet was impressive, but it conveniently caught on fire every time he threw his shield at it.
During the test a bot shot at him and Alex timed it and stepped out of the way. It may not technically count as dodging bullets, but he could easily avoid the shield in the same manner. As soon as Steve throws his shield, Alex would dodge it and shoot Steve.
