In my experience, the TACPs work much more closely with the Army than do the Combat Controllers. Additionally, IIRC, the CCTs have to be qualified as air traffic controllers. The primary job of the CCT is to set up drop zones and airstrips for immediate use for airland. Controlling an airstrike is something that they may do, but not necessarily their primary job. Also, IIRC all CCTs have to be airborne qualifed and get to go to a bunch of hooah schools which the TACPs may or may not go to depending on their particular assignment and desires.
The TACP (1C4 AFSC) is primarily there to work in the air liaison business with the Army doing whatever needs to be done to effect that liaison--from controlling a CAS strike, to requesting recconnaissance, to helping plan deep interdiction. Try googling ROMAD. Many of today's TACP enlisted personnel take affront at the term ROMAD from Viet Nam and perhaps even earlier, but it does describe what a junior enlisted 1C4 does a lot of, Radio Operator, Maintainer, and Driver. Several years ago, only "rated" officers (Air Liaison Officers--ALOs) could control an airstrike, but today, MOST of the qualified Terminal Attack Controllers are NCOs and most of the ALOs are in the Command Post advising the Army on employment of airpower. A new 1C4 would start out probably working with an experienced NCO 1C4 who is a JTAC (Joint Terminal Attack Controller) and after becoming experienced and attending some additional schooling, would himself become a JTAC. Eventually, as a senior NCO you would move up to working as an advisor like the ALOs (most of whom only do one or two tours out of the cockpit in this business--though there are some exceptions).
If you are going into the WAANG, are you going to the 111 ASOC? if so, that is another venue for 1C4s, working in the Air Support Operations Center. This is basically the net control for the Close Air Support Air Request Net and works the issue of assigning various flights of aircraft to support Army requests for air support. Normally, most 1C4s will have one or more tours in the ASOC during their career.
In most cases, being a TACP is being in the ARMY Air Force. Most active duty assignments are on Army Installations rather than Air Force Bases. When the Army goes to the field, you go to the field, when the Army has to carry a ton of c**p you will have to carry a ton and a half of c**p because you have to carry basically everything they carry plus the required radios to work the air request net. All that said, i enjoyed the almost 9 years I spent working with 1C4 TACP folks in an Air Support Operations Squadron & Group.
