That about makes you the perfect guy to figure this out. IMHO, the best guys in leadership most often did not want the job. They just knew how to do the job right. Sounds like that could be you.
So look, Harry buys a Polaris. He needs an EM warfare/scan guy, a navigator, a couple engineers, half dozen turret gunners, a really sharpshooting gunner for the chin mount and missile launchers, and a Master Sargent to lead a couple other PCs each leading small teams of marines. About a dozen guys, presuming the marines are NPCs. The captain of that ship knows he's not going to get the same dozen guys every time he has available, so he'll be drawing from some sort of lists of who can do those jobs. If he can't organize that kind of small group regularly, he won't be playing his game regularly. He'll throw up his hands and go solo mining. This problem grows exponentially with growth in ship/crew size.
One of the huge advantages we have in TEST is the raw SIZE of the org. How much work could it be to find the guys who know how to do those tasks, and ask them to design one to two hour training programs that people get certified from once they invest that time? Once it is up and running, players will take pride in their training and it will evolve. It my take some care to assure it doesn't evolve into something anal, but just saying true, Montoya is the last thing from anal. I doubt he'll let that happen.
And I'm thinking of this now not because of the Polaris, but because of the Tonk. It really needs three trained players to be effective, or maybe five for three tanks. The tanks aren't worth anything without skilled players, since nobody I know likes to lose.
