Members of the Qatar Emiri Air Force practice a diamond fire team movement during joint interoperability training April 14, 2015, at Al Udeid Air Base, Qatar. This type of movement can be used during patrols or moving through buildings. Airmen from the 379th Expeditionary Security Forces Squadron shared techniques and procedures with members of the Qatar Emiri Air Force during this joint training. Training enhances the interoperability of both the U.S. and its host nation partners and helps improve bilateral relations by sharing techniques on how each country operates.
