Homeland Security Advisory Council's five to three level color code advisory system recommendation = no go The Homeland Security Advisory Council's recommendation is not workable. It has no chance of adoption by the military messaging community that has along with NASA and its five level tone based messaging system and the National Undersea Research Center NURC's five level scheme would be broken. The military structured messaging systems drives command and control system development through mission thread (work flow) libraries to include funding lines that simply cannot adopt this change as it breaks machine to machine level processing based on precedence on time established INFOCON levels. This recommendation also breaks down messaging between five main countries -- actually more than five. Changing this long standing system WILL BREAK mapping & machine to machine numeric processing… NASA & NURC's undersea tone based messaging should be used for the blind and for situations that visual information is unavailable e.g., power outages, smoke, dust... This recommendation is DOA. Precedence is a simple ordering, based on either importance or sequence: - Message precedence of military communications traffic - Order of precedence, the (ceremonial) hierarchy within a nation or state - Order of operations, in mathematics and computer programming CCEB military precedence: The Combined Communications-Electronics Board (CCEB), a five-nation joint military communications-electronics organization (consisting of Australia, Canada, New Zealand, the United Kingdom, and the United States), uses the following message precedence designators, in descending order of PRECEDENCE: INFOCON levels: NULL / NORMAL / ALPHA (increased), BRAVO (specific risk of attack), CHARLIE (limited attack), DELTA (general attack). http://www.scribd.com/doc/19945401/Homeland-Security-Advisory-Counsel-3-level-color-code-no-go
