"BELIEVE IT OR NOT, YOUR CO CAN ORDER YOU TO BE A HUMAN GUINEA PIG"
Technological detection devices not totally to be relied upon in case of chemical attack. What are deemed and described as "human guinea pigs" subjected to what was previously a hostile environment [CBRN]. Unmasking protocol to be rigidly followed.
Consider unmasking protocol as taught to leaders [CO] of U.S. Marines:
I. Designate two-three Marines.
A. Brief them on the procedures to be followed.
B. Have them sit in a shaded area out of direct sunlight.
C. Ensure they are unarmed.
II. The selected Marines will.
A. Take a deep breath.
B. Keep their eyes open.
C. Break the seal of their masks for fifteen seconds.
D. Then reseal and clear their masks.
E. Wait for ten minutes.
* Unit commander [CO] choosing those personnel to unmask from the least critical troops within the unit.
* Eyes open when breaking seal of mask. Check for the presence of mustard agent in aerosol form. Exposure to aerosol mustard agent can begin to cause blindness with seven seconds.
* That ten minutes [IIE.] having elapsed, selected personnel can then totally unmask an be observed for another ten minutes. A lack of symptoms to chemical agent poisoning indicative of a safe surrounding environment. The rest of the unit then able to also unmask and do so safely with assurance.
DO NOT THINK THAT AMERICAN MILITARY PERSONNEL BEING DESIGNATED AS "HUMAN GUINEA PIGS" UNUSUAL OR EVEN ILLEGAL. BY LAW AMERICAN MILITARY PERSONNEL CANNOT REFUSE MEDICAL TREATMENT OF ANY SORT. MEDICAL TREATMENT SO BROADLY DEFINED AS TO MEAN ANY SORT OF PROPHYLACTIC MEASURES.
YOU MUST OBEY! THAT IS THE ESSENCE OF THE SOLDIERLY ETHOS!
