Go navy or air force and get a technical skill

Clean weapons, write home.

My parents moved and left no forwarding address.

Home is, back in the world, not a house to me?

Guard duty and drink. Play war and drink. Go to town and
drink more.

Lots of busy work and it’s going to suck to be a PVT.

Tell him to pick an MOS that they can learn a trade. It works! I’ve done it a couple of times

Get trade air force or navy.

Signal, MI and all the logistics MOS's come to mind.

World travel (snicker). Suggest him to go for something like aviation mechanics or electronics technician. Navy ships are self-contained multi weapons platform. Every system has a civilian use. Each ship has a high voltage electrical system, cutting edge electronics that need maintenance (maintenance is pretty much the Navy's mantra), diagnosis and repair. Aviation mechanics are set for life when it comes to a trade that will allow someone to work anywhere in the world. One hitch will get you in the door. Who knows, may it will be his first career, and double dip by putting another 20, and retiring with both a work and military pension. They are very secure upon retirement.

My two cents.

My rating was AMS (Aircraft Mechanic/Structures)

Best decision I made. Navy taught me repair techniques for damaged airframes and components then let me get four years of practical experience.

Got out and went to work at a repair station, got my A&P, went to work for AirCal and then American.

I ended up working as a Union mechanic for thirty years and retiring at age 60 drawing on my pension.

My $.02

I'd advise a trade specific high demand NEC. (Naval Enlisted Classification) such as electrician or Air Traffic controller.

Infantry training is often more difficult than the real thing. Your unit will cycle through numerous training centers like JRTC and NTC and also lots of field training at your local installation. It's frustrating for an infantry soldier to constantly be going in the field as you watch your rear-echelon comrades stay in their barracks. Your comment about infantry being a janitor is uninformed and incorrect. Your everyday U.S. infantry soldier is a highly trained and disciplined individual and his life is not easy.

I was being sarcastic

An attempt at humor.
