The army is rebuilding around 43 ground combat brigades, each with between 3,500 and 3,900 troops. The goal is to have the brigades operate far more independently than existing ones, which rely heavily on their larger division structures to function in a war zone.

The new brigades are built around one of three designs:

-light, primarily infantry.

-Stryker, built around the Stryker armored vehicle.

-heavy, which have tanks and armored infantry carriers.

That compares with 13 designs among the 33 old Army brigades, each with between 3,000 and 5,000 soldiers.

Some the changes are under way; others will not be completed until 2009.  (more)
