How did the American imperialists recruit soldiers during World War II, and how did they reach tens of millions by the end of the war?

At ordinary times, there are "procedures" for the conscription of American imperialists, such as first conducting a theoretical examination (determining the arms to be placed after the soldiers join the army) and then conducting a physical examination (directly excluding those with a history of drug abuse and physical disability); In addition, the age of conscription is 18-25 years old.

However, under special circumstances, such as World War II, for the sake of war, the U.S. imperialists will "appropriately" relax the conditions for conscription, such as lowering the theoretical examination score, "releasing water" during physical examination, relaxing the age limit for conscription (raising it to 39) and so on.

In addition, the U.S. imperialists will also make great efforts in conscription, such as playing "patriotic cards", improving the treatment of soldiers and posting conscription advertisements everywhere. As for those who meet the conditions for conscription but explicitly refuse to join the army, the US imperialists will punish them as "anti-war" and forcibly recruit them. Those who deliberately escape will be punished as criminals.
