I know it's nit picky but here's a Scenario. You are a military pilot with a FAA CFII and you instruct another military pilot in a military simulator but you are not an authorized military Instructor pilot. The way I read the regulation, the instruction is not valid for currency in this case.
In these type of inquiries/postings, I find it better to simply cite the sources then give an opinion.
Yes, you cannot mix mil and civilian instructors and simulators, so if it's a mil simulator it must be a mil instructor.
By "instructor" I meant someone appropriately qualified to instruct in that sim, whether mil or civilian.
A civilian sim must have a current certification letter from the FAA (they do expire). There's nothing that would prevent any mil organization from getting an certification letter, but they may not bother.
But if it's a civilian type (ex P-8/C-40), the sim in use might very well have an FAA cert letter.
