Weapons of Mass Destruction (WMD) are weapons that can kill or harm large numbers of people or do extensive damage to infrastructure, nature, or the earth itself. These weapons include chemical, biological, radiological, or nuclear. This is commonly abbreviated by the military as NBC warfare, or nuclear, biological, chemical, radiological is not included because the military does not use such weapons. These are typically delivered as bombs or missiles such as ICBMs. The effectiveness of such weapons against zombies is very low.
Chemical weapons use toxic substances (chemical agents) usually to kill injure or incapacitate human beings. These agents include harassing agents, incapacitating agents, and lethal agents although the categorization of agents my vary from source to source.These weapons usually come in gas form and can be used by many weapons including artillery, grenades, or missiles. The main problem with the gas form is that the wind can have a great affect on it. Since chemical weapons are specifically designed to harm humans and because zombies aren't affected by them (mostly due to the fact that zombies don't breathe) their usefulness in nil. In fact it would probably bring more harm to the user, especially if they are not wearing proper gear. However, corrosive acids such as sulfuric acid may be beneficial if there is means to produce in bulk and a safe way to distribute and apply.
List of chemical weapons:
- Chlorine-One of the oldest-Used in World War I.
- Mustard gas
Biological weapons use biological toxins or infectious agents to kill or harm humans. These include bacteria, viruses, fungi, and insects (entomological warfare). These will not affect the undead because these only damage living cells.

A radiological weapon is a weapon that, when detonated, distributes radioactive materials across a vast area. Radioactive materials emitted by these weapons may or may not have any effect on the undead. Experiments have been performed to produce large tumors on a zombie's gray matter, but there seems to be no change.
A nuclear weapon is an extremely destructive explosive device that derives its power from nuclear reactions, either fission or a combination of fission and fusion. These have the power to completely decimate an entire city of undead, but be wary, as radioactivity can be present even decades after detonation has occurred. These pose an even greater threat to humans in the explosion vicinity. Zombies are not affected or deterred by radiation sickness or serious burns, but humans are. Although it is difficult to obtain and use a nuclear weapon, it is advised not to even if one has acquired such a powerful device.
