The way that LASORS F4.1(b) reads suggests that you don't even need a Civ IR to commence a TR cse, so long as you have, as a QSP(A), held a Green rating at ANY time in the last 5 years. With the clarification provided above, this means a Green rating on a ME type.
This means that Mylord-Smythe, you ought to be golden, as far as commencing a TR course is concerned. And if ReturnOfX requires his IR for the same purpose, him too (assuming his within-last-5-years Green is on an ME type). If you are talking about exercising IR privileges on your Civ licence, though, that seems to be a different matter.
In short, holding, or having held in the last 5 years, a mil ME Green IR ought to qualify you to commence a TR cse, but doesn't, in and of itself, reval your Civ ME/IR for licence privileges.
Or am I missing something?
