When members of the army are injured in conflicts on the front, time is very precious. The survival of the soldiers depends on how quickly the medical aid crew can get to the wounded soldier. It is expected that the healthcare personnel will act very quickly in order to survive the wounded soldier or to prevent permanent damage to the body. Because, as first aid experts have pointed out, the first hour after the soldier was wounded is the "golden hour". However, it is often not possible for first aid teams to reach wounded soldier in the golden hour because of the modern weapon systems that cause warfare to develop very quickly and are very violent.
