just found out about two hours ago that I will be assigned to Ft. Cambell for my next duty station...what would the best unit to hope for, there, for a 25 B to be in?

160th best unit you can get.

Fort Cmapbell sucks,i would say 4 BDE is the best unit, anyways F.C is full of bullshit,u'll find that out.

It all depends on what you want out of the unit. As a 25U, I've worked closely with a few 25Bs and you guys all have different styles. 160th is high-speed, the four standard Brigades deploy frequently, and there are a few units that hide on Campbell that deploy. Depending on your rank, I would prepare to go to one of the brigades, their slots usually get filled a lot faster.
