On June 28, 2022, the NDUF partnered with the National War College at National Defense University to host a D-Day + 78 Remembrance Reception at Roosevelt Hall. The Remembrance Reception brought together key members of the defense community to commemorate the men and women who served during the D-Day Invasion. Artifacts from the private archives of Major General Milnor Roberts, generously donated by his wife Priscilla, were on display including the original plans of Operation Neptune detailing the plans for the naval and airborne assault on D-Day.
