Simo Häyhä was a Finnish sniper during WWll who was nicknamed the "White Death".
He holds the record for the highest number of confirmed kills of any major war .....505
Simo refused to use a scope because it forced the sniper raise his head in order to see thru the scope.
So consequently, all of his 505 kill shots on Soviet soldiers were with iron sights. .....

During WWII, lots of action took place in urban areas where the cities were turned into rubles. These rubles provided excellent hiding spots to snipers that were carrying out resistance against occupying forces. The distances involved were not much. So it was quite possible to do sniping without scope.
Simo Häyhä did most of his sniping outside urban areas. He used the snow and wilderness to hide.
Being a true sniper is only partly about being a great shot. It is equally about being able to remain unseen by the enemy.
The recent years of fighting in the middle east have made the long shots famous. Carlos hathcock spent 4 days and 3 nights crawlingthru 1,500 yards of open field. The enemy troops almost stepped on him several times. When he killed the NVA general, he had to crawl back out while the enemy troops searched for him. Feats like Hathcock's and Hayha's are what snipers do.
