Being a retired First Sergeant in the Army for 23+ years...best advice is for him to do a ton of research. Recruiters are there to do a job...put numbers in the services. Have him be a bit selective and have a list of MOS's (jobs) written down that he's researched and wants to do. Nothing worse than coming into a service to do a job that you won't enjoy. Also, make sure it is a job that has a civilian counterpart..so when his time in the service is over, he can start a second career in the civilian sector. While a lot of combat arms MOS's have a huge bonus and are a very important part of the military, life after the service is very limited with that skill set.
