Australians took part in all of Bomber Command's major offensives and suffered heavy losses during raids on German cities and targets in France. The Australian contribution to major raids was often substantial, and the Australian squadrons typically provided about 10 percent of the main bomber force during the winter of 1943–1944, including during the Battle of Berlin. Overall, the Australian squadrons in Bomber Command dropped 6 percent of the total weight of bombs dropped by the command during the war. Australian aircrew in Bomber Command had one of the highest casualty rates of any part of the Australian military during World War II. Although only two percent of Australians enlisted in the military served with Bomber Command, they incurred almost 20 percent of all Australian deaths in combat; 3,486 were killed and hundreds more were taken prisoner.
