Nurse Jackie's offensive joke!

genocides can be good, if you kill nazis and soviets

Test time: How many headshots can you get with just one .50 BMG?

I'm no expert. If you line up 3-4 people (of same height) then you can take'em all out in one go.
Still
Wouldn't that be an overkill? I mean 8mm and .45 can do the job. Why waste ammo?

.50 will go through more with one shot, right?

So in the end you're saving ammo

I have better idea. Let's tie 'em. Head pinned to ground facing each one on end of road. Take one Panzer/roller/dozer and run straight over them. Popping heads like watermelons.

Ever heard of the trolley problem? We can just do that with no options. Tie em all to one track.

I doubt it's efficiency. What if the trolley derails after running over a thousands? Wait that'll be same problem if we use tanks/dozers.

Let's stick to guns.

Check out the GR1 Anvil. Ammo might be reusable if we're lucky.

Technically yeah but that would be more expensive. Manufacturing wise. More waste of resources. At this point I believe even mediaeval arrowheads would do the job. It'd be eco friendly too.
