Okay, so we got the FAE bombs and like MINDSPY says, the nukes.

Any chemical agent? Suffocates is what EOM said.

Biological weapons can cause us to suffocate from drowning, but usually it's referred to as drowning. Humm.

A Blood Agent comes close to this, but the main one is a true gas and is slightly lighter than air and dissipates rather quickly. The best agent, the most devastating agent, the most persistant agent is going to be a nerve agent. Convulsions of the body so violent you can snap your own bones without an impact. In it's pure state the rate of action for SOMAN or SARIN (the time from contamination to the moment of death) is around nine seconds. But it is rarely employed pure. At least that's the doctrine. I'm off to bed, I'll take this up tomorrow after school. Only seven more days to teach kids and then I'm off for the summer! Somebody say a prayer for me, that I can make it that long. It's been a very tiring year.

Morning Letitring. I'm catching up again (should be my new freep name) so don't know if your question has been answered. Just trying to research here. I know this info says "drowns" not "suffocates" but...

Suffocates is what EOM said

Choking Agents: These are agents such as Ammonia, Chlorine, and Phosgene. These agents cause damage to the lungs, where the lungs fill with fluid and the victim drowns to death, much like vesicants.

More info.

Suffocates is what EOM said

All the nerve agents cause their toxic effects by preventing the proper operation of the chemical that acts as the body’s “off switch” for glands and muscles. Without an “off switch,” the glands and muscles are constantly being stimulated. They may tire and no longer be able to sustain breathing function.

Well, I'm no doctor, but if you can't "sustain breathing function" I believe suffocation could be a cause of death.
