Character mistake: Bud keeps calling Sarah "Ma'am." Sarah is a corporal. Corporals don't get called ma'am or sir in the US Army. Bud has been in the Army for seven months. No soldier would make this mistake after the third week of boot camp. Anytime you call an enlisted man or NCO sir, you are looking at about 20-50 push-ups or sit-ups to correct you. It's conditioned into you.
