Okay what does Chemical defense do? What is Chemical Reconnaissance?
Should they also have Science: Chemistry or is it mostly just procedure?
Would the MOS be called CBRNE? Should they have Demolitions training if they are dealing with High Explosives?
Here's some information from Wikipedia that I found about the actual military career fields involved with CBRN. These MOS's or AFSC would mean you are a specialist in this field, can train people how to do everything listed below, probably know off the top of your head all of the different possible chemical threats by name and what they can do, etc.
I'm not sure what Chemical Reconnaissance is, but I'm assuming that Chemical Defense is what we would call Chem Warfare Training in the Air Force. It's the basic level of training that every military member in every branch of the military recieves. It teaches the following:
- How to properly wear the NBC suit (wearing it improperly can nullify any protection it's meant to provide)
- How to don in case of an attack (hold breath without inhaling and close eyes, remove mask from carrier and don)
- How to decon yourself and equipment
- How to identify signs and symptoms of exposure, and differences between different types of chemical threats (blood, choking, blister, nerve)
- How to use your chemical anitidote kit in case of exposure to a nerve agent (atropine and 2-pam chloride - and contrary to what you may have seen in The Rock, you do not inject yourself in the heart...
)
- Identification of alarm signals and different MOPP levels (the longest I was ever in MOPP-4 was 12 hours...and it sucked!)
- Proficiency training to perform tasks, combat, and shooting while wearing mask and/or suit
- How to maintain hydration while wearing the suit (you will literally sweat buckets wearing the suit, even in relatively cool weather)
- Shelter procedures and contamination zone egress procedures (how to go through a decon station and remove your suit to either leave an area or don a new suit)
- How to effectively use chemical detection paper, tape, and sniffers.
Chemistry training really isn't a part of the above. Detection of chemical agents is done with tape, paper, or an electronic sniffer. The tape and paper are very similar, except the tape can be attached to equipment and vehicles, and the paper can be dipped into free standing liquid, etc. Though basically the same, they can detect a slightly different array of chemicals, may indicate with different colored reactions, and both are actually toxic to handle for extended periods. Tape and paper will change colors based on the chemical encountered - much like litmus paper. Different colors can mean different agents, but both can provide false positives (for example, hydraulic fluid on the paper can cause the same indication as some nerve agents). The book of Chemical detection apaper (looks like a small notepad), will usually have a chart in the front listing what the colors may indicate. The sniffers will sound an alarm when they detect a chemical agent, and may be able to tell you what type, and maybe even what specific agent - but sniffers can generate false alarms also.
An NBC suit can protect you from just about any type of chemical or biological agent, but has varying lengths of protection based upon the type of chemical encountered. For example, in a gaseous environment the suit could provide protection for over a month (though you may need to change the mask filter more frequently). If exposed to a liquid agent (it actually gets on the suit and soaks in), the suits length of protection is shortened. The suit can also protect you to a certain extent from nuclear fallout. It will prevent inhalation and ingestion of radioactive material, and protect from alpha particles, but it isn't up to protecting you from proximity exposure to a highly radioactive source (beta, gamma - in other words the suit provides no protection from a nuclear reactor, etc.).
