Overall, there were many fights and battles that occurred in different places during WW2 and were fought by different troops. People were able to support their army and war fighters by sending them food or becoming a medic to heal them on the battlefield. People would need medics because after the Battle of the Bulge and the Battle of Kursk, there many people who were injured badly or killed. Fighting over air was very dangerous and useful because the planes could drop bombs or a soldier inside could shoot at the enemy forces from above. Though, being in the air is very beneficial, if shot down, the plane will fall thousands of feet towards the ground, which makes being a pilot very dangerous. Fighting over seas is also very beneficial for the allies in WW2 because the axis had many ships that were very difficult to destroy and could keep firing at the allies ground troops, but the allies' battleships and destroyers could eliminate the axis powers ships really quickly. So, each part of the war effort, fighting over seas, in the air, and on ground, was beneficial for the success of WW2.
