Let's see....The guy with blue is Captain Rex. The guy with the yellow visor and antenna thinger on his helmet is Commander Bly. The trooper with the oragnge on his helmet is a bomb trooper . The guys with red on their armor are in the squad with Commander Fox and I believe the ones with no color are newbs. The trooper with the little round symbol on his helmet is called "Matchstick" I believe. I could be wrong. There is another pilot with similar markings and I get them mixed up. The other troopers with colors or stripes are respective to theur squadrons.
