During a marksmanship test, the task is to hit four small targets (numbered 1 through 4) that retract when hit. Donna calls out the sequence for the shooter beforehand. Before Spike shoots, she calls out 3,1,3,2. That's an impossible sequence, as he would have to shoot the same target twice. (She meant 4,1,3,2 - the clip afterward shows the 4 and 1 targets retracted and the 3 and 2 targets being shot back.)
When Wordy is shooting in the marksmanship drill, he misses two targets. Donna says his weapon jammed and let him re-shoot. However, he fired 4 shots during the drill meaning he actually missed the targets.
