Here are a few of mine.
-The troopers primary romance option is his rifle.
-Republic Special Forces has an IQ test, anyone with a trippe digit IQ ends up in SIS, all those with double or single digit become troopers (seriusly, some of the things the trooper says *facepalm)
-Republic weapons techs never passed basic engineering, after all, I do more damage by hitting my oponent with my rifle than I do by shooting him.
You forgot! A Stockstrike to the head costs two rounds of ammunition!
