Football jocks are said to be a likable lot. They have a natural gift to cause camaraderie. Captain Grid-Iron is a likable fellow at first. He gave up a position in the War College just so he could serve in the field. That alone should have endeared him to his men. What is wrong, though, is that he tries too hard to be likable that he soon becomes an annoyance to his teammates. The fact that he likes to do John Wayne impressions does not seem to help any. When it comes time for fighting, then that's the time they'll follow his charge, without question. He shows that his is true courage and no mere bravado.
Grid-Iron was quarterback for the West Point football team. He graduated in the top ten of his class. He passed up an appointment to the U.S. Army War college, for a conventional infantry command at the company level. His determination to be "where the action is" brought him to the attention of G.I. Joe. According to his file card, his personality is grating, but tolerable. The other Joes think if he would stop trying so hard to be likable, "they might let him play quarterback at the annual G.I. Joe Fish Fry Football Game!"
