With Captain America: The Winter Soldier now having introduced the very cool Falcon, it bears mentioning that the original comic book version of Falc didn't have military training, nor did he get his "wings" until much later. But that doesn't mean the Falcon and Cap didn't become fast friends when they met, or that Falc went into action without knowing how to fight. On the contrary, he learned from the best--even if, at the time, he didn't know it.

Marvel Trivia Question
How did Captain America and the Falcon meet?
The meeting of this famous pair took place during the time when Cap was a victim of the Red Skull's possession of the Cosmic Cube. The Skull had switched bodies with Cap, and transported him to the island of the Exiles--a group of former allies of the Skull who now wished vengeance on him. It was the Skull's plan for the Exiles to mistake Cap for himself, and thus hunt him down and bring about his death.
But when "Cap" and the Exiles battle, he's helped by a falcon which attacks the Exiles and gives him a chance to fend them off and escape. And soon he meets Sam Wilson, who had become a prisoner on the island and was making hit-and-run attacks on the Exiles as well as organizing the other occupants of the island to band together against them. Cap is able to remove the Skull mask and then get Sam's story before making a proposal to him which would end up making the two of them quite a team:
And so Cap begins training the newly-costumed Falcon in hand-to-hand combat, finding him to be a quick study:
Finally, the Falcon is ready to go into action, and he and "Cap" make their first attack as a team.
With the villagers' help, the two are able to send the Exiles fleeing. Unfortunately, the Red Skull (as Cap) has been monitoring the battle, and decides to personally deal with the two, retrieving them from the island and transporting them to a castle in the German alps. There, the Skull decides to switch bodies again with Cap, and Falcon gets quite the surprise:
And, fighting hard against near-impossible odds, Cap and the Falcon do just that. The Skull is forced to flee--and a new hero prepares to take his place in the Marvel universe.
