Re-enactors fire a cannon during a demonstration at Fort Niagara, New York, May 31, 2018. Civilian leaders from the Greater Shreveport/Bossier City area visited the national historic site as part of a Civic Leader Tour hosted by the Niagara Falls Air Reserve Station. These tours allow leaders from other areas of the country to learn more about the mission of other military units and their historical traditions. During this tour, the Louisiana contingent learned about the capabilities and mission of the 914th Air Refueling Wing, the 107th Attack Wing, the Niagara Falls Military Entrance Processing Station and the U.S. Coast Guard Buffalo Sector.
