1. In a few episodes, people refer to Bob and others as simply "sergeant" like INTO HELL pt. 2, Betsy says "Last time I checked, a 2nd lieutenant doesn't take orders from a sergeant" Bob is a level 7 pay grade and Betsy is fresh out of officer canidate school...do they have the cover of being sergeants or do they simply call anybody with a sergeant title (Master sergeant, Sergent Major, etc) simply sergeant.
2. Does Betsy even know that Jonas is in Special Forces?
