Let's go with the
US Army IET for "basic soldier skills". Let's also leave aside physical requirements - unlike many players, most PC should automatially fulfill them.
US Army Basic Combat Training (BCT) consists of:
- intense drill and behavioral exercises and conditioning
- hand-to-hand combat drills
- navigation drills
- first aid drills
- athletics drills
- small unit tactics drills under various conditions, including nighttime, urban, and (where available) high-altitude operations
- firing exercises with a wide variety of small arms
- thrown weapon exercises (hand grenades)
- basic heavy weapons training, especially with anti-tank missile weapons
- survival drills
- basic leadership skills
- equipment maintainance drills throughout
Compare with the lifestyle module "Tour of Duty, UCAS":

Keep in mind that this is basic training; this is followed by Advanced Individual Training (AIT) that is branch-specific. The lifestyle module "Tour of Duty" lists additional skills for each branch that I'll not list here. I'd go with this, to be honest. It seems fairly accurate, as such things should go for a tabletop RPG.
