Two Air Force explosive ordnance disposal technicians use smoke grenades for cover as they run across an open area during a joint service EOD field training exercise at an undisclosed location in Southwest Asia, May 25, 2017. EOD teams from each of the four service branches, deployed to five different countries across the AOR, gathered for joint service EOD training, which allowed for the exchange of tactics, techniques and procedures between service branches.
