Sniper rifle v assault (weapon) rifle

9. The .50 cal shooting down a plane comes from WW2.

I've read things like .50 cals can be used to shoot down aircraft.

The standard M2 .50 machinegun that is still in use is the same gun that was put into the fighter plane wings (4 or 6 of them). (Each had about nine yards of linked ammo, which is where the phrase "gave them the whole nine yards" comes from.)

The modern .50 rifles, which use the exact same ammo as the M2 machinegun, that controllers normally picture when talking about shooting down planes are purposely pictured to confuse the uneducated masses.
