So I know this is a shitpost, but a pelvic shot is taught by some militaries as part of an alternative failure drill (two shots to the chest, followed by one to the head if they continue to be a threat). Its a larger target than a headshot requires, and is rarely protected by armor. Plus, if you miss, the shot is more likely to hit the ground instead of continuing flight well beyond whoever you were shooting at.

So shitpost or not, its not the worst place to shoot.

or end up Robocop scene 27ing (don't watch that unless you're prepared to see a whole lot of dick get shot off)
