Continuity mistake: After Derrick reveals to Randy that he cheated for him in basic so he would pass his marksmanship test he smashes his cake, causing some of it to splash on Derrick's uniform. At first frosting is all over Derrick's top but seconds later there is much less of it on him. There wasn't enough time for him to wipe off the frosting between shots.
Factual error: While the brothers were fighting with each other they are interrupted by the flag being raised and stopped fighting to salute the flag. The wrong song was playing when the flag was being hoisted. On Army bases Reveille is supposed to play during the raising of the flag but the show had the end of "To the Colors" (what is played when it is being lowered in the evening) playing instead.
