I like using a pillow to stop someone's snoring, sure, they can't breathe, but the snoring stops. No, don't do that, you let go of the pillow when they start struggling. ????

gently roll him off the bed.. the thump will quiet him down a bit..

Superglue works every time.

No help right now, but get some noise cancelling headphones and a music player or phone.

Slight nudge in the ribs, but please change spots so there is no evidence later!

Say the persons name softly, not enough to wake them.

My stepson had a roommate in college who snored and he would just throw something at him and it would startle him but not wake him up and he'd be quiet for while.

Aside from ear plugs someone else suggested -- you can buy inexpensive "white noise" generators that usually have a selection of background noises that can help drown out intrusive noises and make sudden noises less noticeable. My wife loves hers, it has a selection of sounds like gentle rain, surf, actual white noise, etc. We have a battery-powered version we take on vacation.

There is no perfect answer. I managed to fanagle a CPAP device for myself despite that I technically don't have sleep apnea, and eventually found a "nose pillow" style mask that doesn't bug me too much. This allows my wife to actually sleep in the same bed with me as it stops my snoring. Although I still stagger out sometime after 3 am and crash on my office futon because I get up to pee too often (I'm 61) and she sleeps especially light after about that time.

Getting old is a bitch. It's one compromise and/or indignity after another. Fortunately there are a few upsides too. If only I could remember what they are.

Turn him in his side

Do you not have access to firearms? (Jk)

First off, thank you for your service! If you can roll them on their side, or slide a pillow under their head it may help.

Put firm pressure on the pillow that you put over their face and hold steady for 10 minutes or more.
