Shock and Awe The AUSA Annual Meeting felt the imprint of the country’s 21st-century wars almost immediately. The 2001 show was scheduled about a month after Sept. 11, and was canceled, Thompson said, “because the Army was in the midst of begin- ning initial deployment to Afghanistan.” It returned the follow- ing year, and since 2003, when the United States went to war in Iraq, attendance has more than doubled. AUSA 2011 drew about 38,000 people — 16 to 20 percent of them active-duty or reserve military personnel, according to Thompson — and for the first time, filled all five exhibit halls at Walter E.

Long gone is the olive drab of the classic uniform, replaced by a thousand shades of khaki, for an army that for the foreseeable future seems like it will be doing most of its fighting in the desert. Wandering around the expo space, you saw uniforms, sun-

glasses, irrigation and communications systems, and other ma- teriel, along with displays for veterans’ benefits, mental-health services, and professional development. But what registered most strongly were the weapons and heavy equipment. The three Bradley vehicles — squat, sand-colored tanks — greeted you as soon as you entered Halls D and E upstairs at Walter E. Washington, part of BAE Systems’ block-sized exhibition space, which also included a Silver Fox unmanned aerial vehicle (UAV),
