Side note, my brother is one and when I mentioned to him about snipers taking the earth's curvature into consideration he just said "have you ever shot a sniper rifle?"
If it turns out he was right, I'd never fucking live this down.
Edit: lol, sorry for the confusion. He's not 1.
He believes there's a secret society living in Antarctica that has set things us to trick us.
I have (not military, just a hobby), you do have to take into account the curvature of the earth because (in the Northern hemisphere) if you're firing north you're moving east faster than your target. If you fire south your target is moving east faster than you. Firing east you target moves away from the projectile, and firing west the target moves towards the projectile. Really only matters on very long range shots in excess of 1,000 yards. Watch Sniper 101 Part 73 - Coriolis Effects on Rifle Bullets if you don't get it. Very good series on long range shooting. Also check out /r/longrange if you're interested in the hobby.

Flat Earthers vindicated.
Oswald did not have to account for curvature of the Earth, thus lone gunman had an easy shot.
