There are two types of medics: the first are those who follow the army on the attack and work with the army to save lives; the second are the medics in the field hospitals.
The second type of medic is the physician in the field hospital, these people are in the rear for the treatment of the wounded. They have better medical equipment and medicines. (The first type of medic, which has just been mentioned, is generally male-dominated, with women playing this role only in special circumstances.) These physicians are in good conditions to carry out more perfect rescue work.
These are, of course, the ones who are truly non-combatants. But don't underestimate them, many of them came out of regular military schools, not from medical schools. This is because the name military doctor is not something that can be produced by a regular medical school. Military doctors not only have good skills, more importantly, they have to have a high quality of heart. They are not simply facing a patient who has been anesthetized, but a living, screaming, hysterical soldier.
Roller Bandage. Usually seven or so, 20 inches in length. I won't go into much detail on this one.
Morphine
(Morphine) is usually about eight, 2g in volume. Morphine itself is derived from Opium (opium), it is a clear powder with a slightly bitter taste, and its main function is to dissolve it in water as is anesthetic and analgesic. It is far less addictive than its brothers. (Cocaine, poppy salts, etc., we say in our daily life heroin, is extracted from morphine.)
