Possibly the best sniper ?

Oddly enough, this reminds me of arguments over who is the best athlete in a certain sport when the players were in quite different era. Baseball is the best (worst) at this inventing many statistics to allow cross-era comparisons (which generally fail).

So, due to the evolution of sniper training and equipment, I'll revise my position and say you simply can't claim anyone is an overall "best sniper". Simo was probably the best for his era (say, WWI through Korea), though.
