Thanks for the response 82redleg. I have already the article - found it a couple of weeks ago - interesting and seems to be direction the army should go.

Fuchs: The U.S. Army is calling the Unit of Action either a Heavy BCT, Infantry BCT or Stryker BCT. The HBCT is commanded by a Colonel, has two Combined Arms Battalions (2/M1, 2/M2 companies each), one RSTA squadron, a fires battalion (2/SP155mm Paladin battety), a Brigade Support Battalion, and a Brigade Troops Battalion. The IBCT has the same structure, but with two infantry battalions. The SBCT has three maneuver battalions and it's structure is a little different. If you go to Wikipedia - Transformation of the U.S. Army you will find a write-up on the BCT.
