'U.S. Army Materiel Command. U.S. Army Munitions Command. Edgewood Arsenal. (08/01/1962 - 1971). This film warned that decontamination of vehicles and persons were vitally important after a chemical, biological, or radiological attack. After an attack, units should have marked contaminated areas with approved signs indicating the time, date, and agent used. The four methods of decontamination were natural, removing, covering, and destroying. The first method, natural decontamination, was the easiest of all the methods for removing biological and chemical agents. Wind, evaporation, rain, sunlight and aging all decay biological, chemical, and radiactive material from fallout. The second method, removing, had both a wet and dry process. The dry process required brushing, wiping, or scraping CBR agents. The wet process used soapy water and disinfectant to decontaminate CBR agents. The third method, covering, used waste disposal and earth to cover the radioactive material from fallout. The fourth method, destroying, contained three methods of destruction. Super tropic bleach (STB) worked to decontaminate the Center for Disease Control's (CDC's) Agent B and G categories. Decontamination Solution 2 (DS2) decontaminated all known biological agents on rubber, plastic, and metal. It was best used on tactical vehicles and weapons. Burning was used for liquid agents. Radiological agents could not be destroyed through destruction.'
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare and biological warfare, which together make up NBC, the military acronym for nuclear, biological, and chemical (warfare or weapons), all of which are considered "weapons of mass destruction" (WMDs). None of these fall under the term conventional weapons which are primarily effective due to their destructive potential. In theory, with proper protective equipment, training, and decontamination measures, the primary effects of chemical weapons can be overcome. In practice, they continue to cause much suffering, as most victims are defenceless civilians. Many nations possess vast stockpiles of weaponized agents in preparation for wartime use. The threat and the perceived threat have become strategic tools in planning both measures and counter-measures...

Biological warfare (BW)—also known as germ warfare—is the use of biological toxins or infectious agents such as bacteria, viruses, and fungi with the intent to kill or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities (viruses, which are not universally considered "alive") that reproduce or replicate within their host victims. Entomological (insect) warfare is also considered a type of biological weapon. This type of warfare is distinct from nuclear warfare and chemical warfare, which together with biological warfare make up NBC, the military initialism for nuclear, biological, and chemical warfare using weapons of mass destruction (WMDs). None of these are considered conventional weapons, which are deployed primarily for their explosive, kinetic, or incendiary potential.
Biological weapons may be employed in various ways to gain a strategic or tactical advantage over the enemy, either by threats or by actual deployments. Like some chemical weapons, biological weapons may also be useful as area denial weapons...
