While I may follow your guide as I have no characters in Rhienland, I feel the need to remind you that you cannot tell an indie what ship they can and cannot fly.
If it is green on the tech chart, they can fly it without your permission. You only control the ships your faction members fly.
Not saying you haven't done a amazing job with Rheinland's 5o, but indies =/= faction members. You cannot control the ship they fly. That is the tech chart's job.
