The department says 25-year-old Staff Sgt. Wesley Williams of New Carlisle, Ohio, was killed Monday in Kandahar province when enemy forces attacked his unit with an improvised explosive device.
The News Tribune reports Williams served with Lewis-McChord's 4th Stryker Brigade, 2nd Infantry Division, which deployed last month to replace another Stryker unit in southern Afghanistan.
Williams joined the Army in 2005. He reported to the 2nd Stryker Cavalry Regiment in Vilseck, Germany, in 2006 and deployed with the unit to Iraq in 2007 as a radio telephone operator.
The Army assigned him to Lewis-McChord's 4th Brigade in February 2009, and he deployed to Iraq later that year as a rifleman.
The newspaper says he was an infantry squad leader in this Afghan deployment.
