In addition to bombardment of strategic targets, the 305th BG often flew tactical interdictory missions and supported infantry units. Prior to the invasion of Normandy in June 1944, it helped to neutralize enemy installations such as V-weapon sites, airfields, and repair shops. On 6 June, the unit bombed enemy strongholds near the battle area. During the Battle of Normandy the 305th attacked enemy positions in advance of ground forces at Saint-Lô in July 1944 and struck anti-aircraft batteries to cover the Operation Market-Garden airborne invasion of the Netherlands in September.
