[Independence Day] Why the hell does USMC Capt. Steven Hiller address fellow Marine aviator Capt. Jimmy Wilder as "soldier"

They're jokers. Marines are commonly mistook as the army. Military guys are always busting each other's balls.  He's just doing his pregame routine with his wingman. 

I went to an all branches training school. Had army Sgts call the junior enlisted airmen "air privates".  Anytime, is an opportunity to take a jab at another's or one's own branch.
