U.S. Navy D-Day veteran John T. Siewert speaks with leadership from the Army 75th Ranger Regiment following the Pointe du Hoc Ranger Monument commemoration ceremony, June 5, 2018 in Cricqueville en Bessin, France. This year marks the 74th anniversary of Operation Overlord, the Allied invasion of Normandy on June 6, 1944 -- most commonly known as D-Day. An epic multinational amphibious and airborne operation, D-Day forged partnerships and reinforced transatlantic bonds that remain strong today. Overall, U.S. service members from 20 units in Europe and the U.S. will participate in events and ceremonies May 30-June 7, 2018, in almost 40 locations throughout the Normandy region of France as part of Joint Task Force Normandy 74.
