President Obama spent this afternoon visiting service members at Walter Reed National Military Medical Center in Bethesda, Md., meeting with 38 wounded troops and awarding four Purple Hearts. 

The president spent two hours and 40 minutes at the new Walter Reed facility, meeting with 21 soldiers, 13 marines, two sailors and two airmen, according to the pool report. Thirty-five of the service members that met with Obama were injured in Afghanistan and three were wounded in Iraq. 

The visit comes one week after the United States marked the 10th anniversary of the war in Afghanistan. Marking the occasion, the president stressed how his administration is ending the war “responsibly” and from “a position of strength” and thanked service members and their families for their sacrifice.

The Pentagon reports that 46,542 service members have been wounded in connection with the Afghan and Iraqi wars.

Today marked the president’s 11th visit to the military hospital, according to unofficial White House historian CBS’ Mark Knoller, and his first to the hospital’s new location.
