I thought to disable guards or patrol officers...the military trained covert people to stab at an upward angle into the chest, puncturing the lungs. So the avioli fluid would fill the sacks of their lung and puke/choke on the fluid+blood mixture in the lungs. This would keep them from screaming or running away, at least thats how I heard they did it in vietnam.

Many famous fighters have done this (roy jones jr, chuck norris, Morbicid, etc)"
