What is China's helicopter for battlefield rescue missions, and what is the difference between it and armed helicopters?

Armed helicopters are divided into specialized and non-professional armed helicopters of two kinds, Wuzhi 10 belongs to the former, can not transport people or things, it is all above the airborne weapons system, Wuzhi 19 is non-professional, but stronger than the armed transport firepower, because it is used for combat airborne equipment than the armed transport aircraft and ordinary transport aircraft, is to compensate for the lack of the number of Wuzhi 10 and the conversion, above the people and goods can be carried When not performing combat missions, it can perform reconnaissance, fire correction, transportation of materials and personnel and battlefield rescue. Armed transport aircraft is in the ordinary transport aircraft loaded with a little self-defense weapons, combat effectiveness is weak, can protect themselves even good. Transportation aircraft is a transport people or cargo, replenishment of ammunition, transport lifting weapons and equipment, basically no combat power, the need for others to protect.
