What do you talk about with military guys?

Ask targeted questions about his feelings, spiritual beliefs and changing perspective about life when he brings them up with you. If he talks about the risks he takes, ask him how they affect his feelings about your relationship. Discuss whether his feelings have any spiritual or emotional meaning for him.

How do you ask someone if they are in the military?

MOS/Rate/AFSC etc. is ok for the personnel types and for a shorthand for what your job is, but when talking to others, not of your field, just ask or tell them what your job was/is.

Does the army require you to have a cell phone?

Historically, standard Army basic training rules allowed for well-performing platoons to be rewarded with phone calls home on Sundays. Recruits in many Army basic training platoons are now allowed to use personal cell phones to call friends and families, send text messages, and update their social media status.
