Since the start of the war, on land, both sides suffered, but it is the German and Soviet soldiers that paid the most this conflict of giants. During the last year, a first Axis country, Finland, was conquered, after a long and heroic, but in the end futile, defense.
In the air, the Allies are dominating the skies almost uncontested, and Axis loses are staggering. Allied loses also are quite high when adding up US, UK and USSR loses, but they can afford them much more easily than the Axis.
Only at sea did the Axis inflict some serious damage. Although the surface fleets of Italy and Germany are only a shadow of their former self, they both still have a moderate submarine force. In the Atlantic, German U-boats have sunk over 46 million tons of merchant shipping and about 350 escorts of all type. Luckily for them, the Allies had planned and were not caught unprepared, managing to deal with the loses.
