SAS - The Special Air Service, most famed of the British special forces. Serious fucking badasses.Paratroopers - an elite division of the British Army specialising in parachuting into combat zones, hence the name. Often the first ones into a fight. One of the three/four (one division is a territorial army division, or some such, which I believe means they stay on British soil and dont deploy abroad) divisions is part of the SFSG, the Special Forces Support Group, and work closely with the SAS on many operations.
Okay that makes sense now.
SO ANDAE. Since you trained me in combat and everything
I feel that perhaps our characters could have a sort of affectionate-banter type of relationship-- With Frakie's personality, she would have given any authority figures, namely Marcus, complete and utter hell, but with her extensive skills, Marcus would have begrudgingly put up with her attitude, while keeping her in line where it was needed. Because of this assumed backstory, perhaps they could give each other shit, but honestly have admiration for each other, in one form or another.
