Lyudmila Pavlichenko is the highest-scoring female sniper on record, with a count of 309 confirmed kills, 36 of which were enemy snipers. And while it's unfair to compare real-life soldiers with superhuman Hollywood killing machines like John Rambo, that's actually more people than Rambo killed on-screen -- in fact, it's more people than Stallone has killed in all of his movies combined. That's right -- this woman shot more people in real life than a man who was only pretending to do it with the aid of special effects, editing, and extras who weren't even trying to kill him back. They couldn't show Rambo killing that many, because it just wouldn't have been plausible.
Also, there's no mention of her sounding like she was perpetually mid-stroke.
Pavlichenko was already an accomplished sniper by the time she was 24 and Hitler decided that Russia was the final boss battle of his world domination game. And where a fictional badass gets his kills by mowing down rows of bad guys running mindlessly into his machine gun, Pavlichenko took hers out one at a time, carefully and patiently. Of her many duels with German snipers, Pavlichenko recalled the longest lasting over three days.
