What medical means did the front-line military doctors have in World War II?

In World War II, many people died of lack of good medical facilities, including a good medical environment. As front-line military doctors, facing many soldiers in their hands, their first reaction is to stop bleeding first to prevent excessive blood loss and death. On the battlefield, there is no time for you to do other unnecessary things, only to stop the bleeding first, and then go to the rear hospital for surgery to take out the bullet, so it's ok, and even there is no anesthetic during the operation.

Medical treatment on the battlefield is the simplest dressing, and it is almost impossible to have surgery. You have to wait until after the battle, guessing that you may go to the rear for further treatment. At the same time, there was a shortage of medical staff. If you are seriously injured, I will simply dress you up and let you die. At the same time, drugs were very limited at that time. If you are seriously injured, you can't spend a lot of medicine to save you. If you spend enough medicine, many people would rather die directly than be seriously injured and wait for death there.

In fact, in the war, the most commonly used medical means of military doctors is dressing to stop bleeding.
