Dear toonicegay,

Killing silently is a tall order, but a quick look at an anatomy chart will show that the larynx is an easy enough target—providing you can make a stealthy submerged approach, sneak up on your victim, and catch him unaware. Once that's accomplished, grasp his hair as close to the scalp as you're able to and yank his head back while using your Ka-Bar combat knife to make a lateral cut across his throat. Make sure you sever both the carotid artery and jugular vein while piercing the windpipe, and press hard; the larynx is a tough, rubbery piece of tissue.
