Members of the Guatemalan Inter-Agency Border Unit (IABU) prepare to fire M1919 Browning .30-caliber machine guns at the Guatemalan military academy, San Juan Sacatepéquez, Guatemala, during IABU training, May 20, 2013. The U.S. Army worked with the U.S. Border Patrol to train the newly formed Guatemala IABU for the mission of interdicting the flow of illicit activities on the Guatemalan borders. The weapons are mounted on Jeep J-8 vehicles that were specifically bought for this purpose. (U.S. Army photo by Kaye Richey/Released)
