I think we make a mistake with our snipers as well.
A head shot, in the minds of the target’s comrades, instantly and painlessly removes the jihadist from Hell on earth (living in a primitive and brutal muslim land) to a paradise of literal fountains of milk and honey, surrounded by 72 virgins and 18 ‘young boys like pearls’ eager to satisfy his every sexual desire.
Aim for the small head guys!
Now Achmed’s buddies get to see him scream and curse, watch him slowly and painfully bleed out, with the sure and certain knowledge that if, if he makes it to paradise he will have no ability to enjoy the virgins and young boys.
And if Achmed manages to survive, he’s a living example that allah is not merciful. He’s an object of pity and disgust, not someone to be emulated.
Our snipers aren’t trained to torture their targets, just remove them as a threat.
