Also should I put these skills (Runner, Psy_Ops, Combat_Engineer, Improvised_Munitions) under the Skill section on the sheet?
Those go on the specialties line near the top of the sheet.
Runner +1 to MOBILITY rolls for running.
Psy_Ops +1 to PERSUASION rolls for changing someone's mind about a particular issue.
Combat_Engineer +1 modifier to TECH rolls for placing and disarming mines and explosive device, and to RECON rolls to avoid mines.
Improvised_Munitions +1 to TECH rolls for making zip-guns and IEDs.
(A zip-gun is an improvised single-shot firearm using parts easily found at Home Depot)
