In MW3 terms Blue Collar -> Military School -> Ne'do-well -> Academy (W/OCS) -> TOD.
MW1 just a Dude with the Academy Package Extra CP doped on Pilot, Gunnery, Leadership, Tactics, Rogue and Streetwise
MW2 Advanced University with Basic, MW and Leadership packages and picked up some Rogue skill with leftover Skill points.
after being thrown out of Military School at 15 he ended up a drifter for just under a year till washing up on Solaris where he hustled Mech Sims and Gambled, around his 16th birthday he got tricked in to taking a Junker Blackjack as payment for a bunch of markers he'd collected, decided to cut his losses and go strait and went to the academy like his Ancestors, but the only one he could get in to was Blackjack because of his "Discipline Problems". joined the LCAF as the 3SW was winding down, pulled some Scout duty when his Mech wasn't working, claimed a 2nd Blackjack on one of those asigments wile raiding a Pirate band, after being forced to reserve his commission a bunch of parts approximating a Blackjack fell off the back of a Dropship and he being a good citizen wasn't going to leave them around where someone could trip over them. now he's out on the edge of the periphery giving Pirates a kicking when the Government wants to pay up.
He's very early 20's, very fair almost pale skin jet black hair, until of late it was a unruly mop but he has shaved it along with his Stash and Goatee (that he realized looked silly and not rakish as he originally thought).
the Unit has no Dropship let alone a Jumpship, no Medic, a couple of Scouts, two Techs and a Astech, one of the MW's is a former Tech the other a former Scout and the last is a sketchy ex-Freelancer from the wrong side of the periphery boundary.
