In 1939 the active United States military totaled 335,000, and during the conflict more than 16 million men and women had served. Tens of millions of men and women throughout the world were in military service in other nations of the world.
At war's end America had sustained 1,000,000 casualties, nearly 300,000 killed and 700,000 wounded. Throughout the world it is estimated that the total of military and civilian deaths amounted to over 53,000,000. In the countries where battles were fought millions of people were left homeless and entire cities and towns had to be rebuilt.

Worldwide over 254,000 aircraft fell from the skies and over 11,000 naval and merchant ships now rest on ocean floors.
