Besides strategic missions, the 707th often carried out air support and air interdiction operations. It supported Operation Overlord, the invasion of Normandy in June 1944 by attacking strong points, bridges, airfields, transportation, and other targets in France. The squadron aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. It dropped supplies to Allied troops near Nijmegen during Operation Market-Garden in September. The unit bombed marshalling yards, bridges, and road junctions during the Battle of the Bulge in December 1944 and January 1945. It flew low level missions to drop medical supplies, arms, and food to airborne and ground troops near Wesel during Operation Varsity in March 1945. The 707th flew its last combat mission on 25 April, attacking a bridge near Salzburg, Austria.
