Ah.
I massively disagree about Tutor being bad. CF any technical, vehicle, or knowledge skillsoft at time of build. Can then instruct (virtual instructor program). Can use Proficiency to act as a user skillsoft, letting the user test against the skill at half the sprite's rating. Due to tutor nature only complex action or extended tests apply -- if it needs to be free or simple you're out of luck. Still, look at the list.
Technical: Armorer, Artisan, Chemistry, Cybercombat, CyberTechnology, Data Search, Demolitions, Electronic Warfare, First Aid, Forgery, Hacking, Hardware, Locksmith, Medicine, Mechanic (Aeronautical, Automotive, Industrial, Nautical), Software.
Vehicle: Gunnery, Pilot (any).
Note that because you can "lend" your sprites you can use this to instruct team-members, or give another team member a needed skill to complete the mission. Or (per earlier discussion) add the optional Command, give it the CF Gunnery, and let it run Remote Command your drone in a firefight.
