Retired U.S. Navy Explosive Ordnance Disposal Technician 1st Class John Kremer (center) shares a laugh with the opposing Netherlands team during the sitting volleyball portion of the 2014 London Invictus Games, Copper Box Arena, England, Sept 14, 2014. Prince Harry was driven to bring the event to an international audience following his inspirational visit to the Warrior Games in Colorado in 2013. The event in London will bring together for the first time servicemen and women – both serving and veteran – from 14 nations. The Invictus Games will spotlight the sacrifices these men and women made serving their country, and their indefatigable drive to overcome. (U.S. Air Force photo by Senior Airman Justyn M.
