If you saw only what the networks reported, you would believe that every American pilot who fought with the Peloran was a Cowboy. That is not entirely accurate. And all of us did not pilot Avengers. No single weapon can be used against all enemies you know. The Avenger is an excellent fighter, but Marauders are more deadly towards capital ships, and Shooting Stars are powerful military transports. Combined arms attacks are usually far more effective than more singular attacks, and we brought every advantage we could find to the Hyades with us.
