An awesome suggestion: Soldiers will react to their wounds. If you shoot their legs, the soldiers will become limb or have difficulties to walk. If you shoot their arms, the soldiers will drop their weapons sometimes and unable to wield weapons again. Some soldiers don't die, instead they will be wounded and can be healed by medic. Wounded soldiers sometimes surrender. All wounds can be healed by medic, some wounds need longer time to heal. Wounded soldiers will shout "medic". Medic can also pull wounded soldiers to somewhere saver before healing them.
