The Army is scrapping two heavy brigades for Stryker units:
The move to convert two heavy brigades to Stryker units signals the Army's shift toward a lighter, more quickly deployable formation that is infantry-focused and proven to be highly mobile in diverse environments.
And it further reduces the Army's number of heavy brigades. Defense Secretary Robert Gates had announced in April that the Army would hold the total number of brigade combat teams at 45 rather than the planned 48, and the Army nixed a plan to grow three heavy brigades.
I'll say it now: Stryker units are to Iraq and Afghanistan as airborne units are to WWII. The future of irregular warfare is here, and it's on eight wheels.
