The Army doesn't have JTAC's they come from the Air Force. I think command staff (I think, since im not on command staff) is going to try and find a work around, when they are needed. Lots of other stuff to figure out before that bomb needs to be dropped.
They may be re-designated to F.O. (13F), as they handle Artillery, mortars, and close air support. http://usmilitary.about.com/od/enlistedjobs/a/13f.htm
Completely IMO
Air Force a/c. Air Force TACP.

For the few that may be unfamiliar:
"A USAF TACP, is usually a team of two or more United States Air Force TACP journeymen or craftsmen (AFSC 1C4X1) aligned with a conventional or special operational United States Army combat maneuver unit to advise ground commanders on the best use of air power, establish and maintain command and control communications, and provide precision terminal attack guidance of U.S. and coalition fixed- and rotary-wing close air support aircraft, artillery, and naval gunfire. A TACP always includes at least one Joint Terminal Attack Controller (JTAC) qualified to control attack aircraft. It can also include an Air Liaison Officer, who is often JTAC qualified and serves in a senior advisor capacity. JTAC teams are primarily stationed with and support army combat units."
