Probably pretty much the same today as 20-30 years ago. An armored cavalry regiment is, primarily, tasked with the job of fighting 80-100 klicks behind enemy lines, disrupting communications, reconnaisance in force, and causing general mayhem until they take approximately 80% casualties, then trying to fight their way back to friendly forces. They use tanks, Bradleys and APCs for transport (probably, mostly APCs). As a new grunt, he'd be at the bottom of the food chain. Scout - think point man (first to get shot). Basically, expendable cannon fodder. I remember using an M114 Armored Scout Vehicle (a small, lightly armored, faster than an M113, tracked vehicle with armor plating that would probably stop a 7.62 x 39 round, but nothing much larger) many years ago when TDY with an Armored Cav regiment - fun, but you wouldn't want to get into a heavy fire fight in it. Translating to civilian jobs? Can't think of too many positions for guys with that background, specifically. Now, please don't think I'm anti-military, quite the opposite. I strongly encourage young men to join the service, and back them 100%. I do recommend independent research, though, as I doubt recruiters have changed their SOP much over the years - signing people up is their primary objective, not fully disclosing everything about the "option" they sign up for is not always number one on their priority. Also, unless things have changed dramatically, the services do not absolutely guarantee that any enlisted person will get the training/assignment that they desired upon joining - it is all determined by the needs of the service at any given time. I wish him good luck, but wouldn't count on that MOS for developing any marketable civilian job skills, other than inducing him with a lot more maturity than he would develop flipping burgers at the local McDonalds.
