Metal Gear Solid 2: Sons of Liberty

The easiest option is to run up to the enemy from the front and crack him in the balls (you can do it from behind). One hit is enough, but you need to hit it in a certain place.

you can also jump on top of them, hanging from your arms, or finish them off hand-to-hand

if you have time to shoot at the exclamation and question marks, you will see the soldier’s secret state “drug addict”... in this form you can do whatever you want with him

You can also hit with a stinger and immediately knock down
