I'm pretty much a "task-oriented" guy, so I don't mind the "concept" of "jointness". However, my experience in OIF I made it seems like "Joint", at least in terms of CJTF-7 meant "people a long ways away who have no connection or stake at what was going on in theater interfering with ops while building their own empires." The only thing that I "saw" CJTF do, was to intercept stuff I'd ordered for V Corps, and confiscating 1/3d of it for themselves, or confiscating anything they thought was "neat." They were kind of like an organized crime gang, in spiffy uniforms and with a dessert bar at their mess hall.

My favorite quote of the war was "The 'L' in CJTF-7 stands for Leadership."

I remain a "joint" skeptic, unless you want to talk about direct coordination issues. I've been "joint" for a while now and seldom had difficulty doing direct coordination.
