in order to test the effects of an incapacitating drug under field conditions a simple exercise was devised
the troops were given the same quantity of water to drink before each day's exercise
unknown to the troops, the drug was added to the water on the second day

the first effects of the drug make their appearance
the men no longer take cover
they relax and begin to giggle
losing all contact with reality

the troops have lost their air of urgency and many men are laughing
meanwhile, radio communication at the beaches has become difficult
if not impossible
men with no specific task in the corps have relaxed with laughter and inconsquential behaviour
though they are still capable of sustained physical effort

seventy minutes after the administration of the drug
with one man climbing a tree
the troop commander gives up
saying i cannot do anything about this
i cannot control the men and i can take no action myself
i am wiped out
i'm taking pause
