The TACP career-field as a whole is really in a state of change. The pipeline is changing and morphing into what I understand is for the better. In my opinion ALO's are not needed at anything below the Brigade level, which seems to be the current trend. Additionally, ALO's should not be controlling air. Their job is to set in a TOC to liaison, provide support to Battalion and below TACP's, and give the Brigade, Division and Corp commanders advice on air power for the Army's scheme of maneuver.
As far as the PAST goes, I'm all for it it, and it should have been incorporated long ago. Just as the JTAC qual should have been made a part of the pipeline. A ROMAD is great for helping the JTAC, but in reality is not really needed. Any good JTAC worth his salt really does not need one. It would/does make better sense to embed a JTAC team (two qual'd JTAC's) with infantry,SF or whoever..... in case one of them goes down.
As far as women doing it....well....good luck.
