That was my bad. I made an assumption based on what I heard from the individual I spoke to combined with the article and the JTAC + ANGLICO Wikipedia page. and didn’t realize they were separate positions.
1) MISR can be sent to ANGLICO per the detailer. The course is at Fallon.
2) ANGLICO also has position that is normally held by Marine Captains but sometimes Navy Lieutenants which is leading the FCT. This position requires you to be a JTAC and the course for that is also at Fallon.
3) There is also an Air Naval Gunfire Liaison Officer in ANGLICO held by a Naval Officer.
4) If you go on the current open billets pdf for the Marine Corps Reserve, in ANGLICO there is a billet titled “Air Officer” for an O-3.
To be clear I am still not clear on the overlap between some of these.
Adding a better level of nuance here as well - There's a difference between an Air Officer, and JTAC/FAC (by function and billet). Although our ground brethren can use them interchangeably, there is actually a pretty significant difference. The Air Officer is probably one of, if not the most senior Aviator (Aside from the XO) at the larger or purpose built ground units (Anglico, Regiment, MEU, MARSOC). That person is probably a more senior Capt and/or junior Major who works directly for the CO. They're the ones running the entire JTAC program for Anglico to coordinate all aviation related exercises, evaluations, and deployment readiness. They are also typically a graduate of the MAWTS AOD course. I would not expect a sailor to check into Anglico and become an Air Officer (Not by policy, but usually by experience). In the smaller echelons, like Infantry Battalions, it is a crap shoot based off who the CO or OpsO wants in the Air Officer billet (TMS background, timing, and experience sometimes play a factor here).
The FCT Leader as a JTAC/FAC is way more fun on a personal level - small teams, type 1 controls, fun deployments (mostly), and lots of making shit go boom, etc. Air Officer is a little more "career enhancing" but they push a lot of power-points, emails, and attend a lot of planning conferences. CO typically keeps that guy or gal close to the flag pole for his expertise and input. Anglico can get a bad rep and looked at sideways from the artillery community because they're just fire support providers and not cannon cockers. Lots to unpack there about how Anglico does business in terms of unit structure and mission, because they're extremely unique in the DOD. They're often chastised by the other conventional parts of the Marines for various reason, but that is beyond this thread.
