Power Armor use is rolled into Fighting & Physical. Get rid of Marine Discipline, that should be replaced with Strategy (Tactics/Discipline). Close combat training can just be reflected in Fighting/Physical and doesn't require a separate skill choice. The CCG is one of
many Nepleslian pages that require updating and it is on my list of to do's.
Check out this character,
Bernie. He's got the basic 4 skills plus Medical. That should help you figure out what the skills should look like. Also, ignore the Medcanic stuff. Not one of Uso's brighter ideas. *cough*
If I count correctly, that should result in two free skill choices (after adding Strategy).
