Squorch, I will not defend anything the detailers are telling anyone, but the fact remains that historically speaking, the RAG has always had more folks screen for DH than VT/HT's.
I've seen lots of briefs, including listening to CNATRA himself at NHA saying that the Navy needs to increase the numbers of the folks getting DH out of the Training Command. Has the Navy ever backed up these assertions? No.
While I have no actual data to back this up, IMO the VT/HT folks actually have a greater chance of getting DH since they brought the DH Screen Board into existence. It used to be that the Commodores and the Community Manager at NPC would come up with a DH list and get a couple of chops from the Community Leadership.
Now with the board, there is less "good old boy" networking and a more integrity to the selection of DH's. I can't remember any of my DH's in my JO squadron being a VT/HT instructor. During my DH tour we had only 1 VT/HT instructor. That makes about 1 person in about 12 to make DH in my two squadron that was a Flight School instructor. Now they are listed it around 30%? That's a lot better than what I have seen in my limited view.
Back in the mid-90's it was well-known, if you want to be a Skipper some day your DH options were:
1) RAG or TPS (assuming you can get in)
2) Flag Loop
3) Weapons School/Fallon
Needless to say, you can't make Skipper without making DH, therefore, you would want one of those assignments.
Today, the Weapons School/Fallon are probably #1 (still tied with TPS) and the RAG dropped to #2.
I'm sure if you talk to the older folks on this forum, they'll tell you the same thing.
Until you actually see the Navy back up words with deeds (increasing the selection rate for Training Command folks) then you were probably naive in accepting the Detailers word that the VT/HT's will be as competitive as the traditional shore duty assignments.
If you got sold a bill-of-goods, I'm sorry, but the fact that VT/HT's will screen less for DH than the RAG/WWS was proven out long before you or I were ever in the Navy.
