Under current plans, the 8×8 wheeled Stryker armored vehicle will be the future backbone of 8 US Army and 1 National Guard medium armored brigades. The 5th Stryker Brigade from Fort Lewis, WA was the first Stryker unit sent to Afghanistan, deployed in the summer of 2009 as part of a troop level increase. The brigade was equipped with 350 Stryker vehicles. In the first few months of deployment, they lost 21 soldiers, with 40 more wounded, to IED land mines. The losses prompted the Army to examine modifications to their Stryker vehicles, in order to make them more resistant to land mines.
One result is the Stryker hull redesign, creating the v-hulled Stryker DVH. The US Army is now on pace to order 2 brigades worth, as it moves toward the end of Stryker armored vehicle production.
