"Well think of the winter war or vietnam the finnish and vietnamese had little to no artillery, faced with a superior enemy and they still won."
Finland was defeated in the Winter War. In February of 1940 the Soviets launched a massive attack on the primary line of defense in southern Finland, the
Mannerheim Line. When that line began to crumble, the Finns could read the writing on the wall, and they sued for peace on 11 March 1940. Finland lost
portions of Karelia north of Leningrad, a couple of naval bases, and two strips of territory in the north. These territories were the same territiories that
Stalin attempted to negotiate for before the war. Recapturing these territories was the main reason for Finland's entry into WWII (the Continuation
War).
"Remember a wounded soldier is more of a problem to the enemy than a dead one" only applies to armies that are committed to caring for their wounded,
and tactically able to do so. In Vietnam there was an enormous effort to remove the American wounded and give them the best care available. Our enemies in
Indochina (especially the Viet Cong) didn't have the logistical support or a tactical situation that favored intensive care for the badly wounded. I
would also say that there wasn't a moral responsibility either since the North Vietnamese had a philosophy that the individual served the state, and
preservation of human life was subordinate to communist victory. This is similar to the rationale of the North Koreans and Chinese in the Korean War, and the
Soviets in WWII. IIRC, the German sniper doctrine was different on the Eastern Front from the other fronts where they faced Americans and Brits. German
snipers were encouraged to badly wound Western Allied troops but shoot to kill when they faced Russians. The Germans realized that every wounded American or
Brit required the services of at least 19 other personnel. Wounded personnel had to be transported, treated, fed, sheltered, and eventually shipped home.
On the other hand, the medical care of grieviously wounded Soviet troops was not a priority, it was an afterthought.





(the soviets where trying to take over Finland, just like
they did with Estonia). btw thanks for correcting me
. here is an example of the 5.56x45 being ineffective ,
