Before General Schoomaker's tenure, the Army was organized around large, mostly mechanized divisions, of around 15,000 soldiers each, with the aim of being able to fight two major theatres simultaneously. Under the new plan, the Army would be organized around modular brigades of 3,000–4,000 soldiers each, with the aim of being able to deploy continuously in different parts of the world, and effectively organizing the Army closer to the way it fights. An additional 30,000 soldiers were recruited as a short-term measure to assist in the structural changes, although a permanent end-strength change was not expected because of fears of future funding cuts, forcing the Army to pay for the additional personnel from procurement and readiness accounts. Up to 60% of the defense budget is spent on personnel and an extra 10,000 soldiers would cost US$1.4 billion annually.
