Waaayyyyy back in the day, we had an FTS that did a tour in our active duty fleet squadron as a DH.
Actually, it was the predecessor to the FTS, forget what they were called now.
He went on to pick up a flag.
TAR is what you're looking for.
Way back in the day....I stayed in the cockpit the whole time as a FTS while also putting on O-5. I was an outlier. IBB's post is spot on. One flying DH tour, maybe a second if you can finagle it (and that might be a CO tour). Otherwise, plan on managing NROWS.
I will say that at least VR has the various NATOPS evaluators as potential billets at the LOGWING, but that seems like a good deal that I'm sure PERS can kill when necessary.
