Gonna resurrect this thread with some new info.
Talked to a prior-dissociated sea tour detailer and he told me to look into the MISR or Maritime ISR community.
Essentially these guys are experts at shortening the kill chain and coordinating assets.
The Course is at Fallon at NSAWC and they're taught by SEALs.
Hazy as to if they also train you as a JTAC at this course.
Apparently, one of the unit options rather than going to the boat is going to one of the Marine ANGLICO units. They're part of the MEF (Marine Expeditionary Force). Not sure if this is the same Billet as Air Officer for the Firepower Control Teams (FCT).
I've also seen Naval Aviators on LinkedIn with "Naval Gunfire Liaison Officer" at ANGLICO units on their resume's. One of them was a MH-60S guy.
The prior detailer said that MISR was a new and growing community and that commanders are requesting more of them so maybe it's a new billet?
