"The traditional way the army delivers orders to soldiers is by shouting at them. But researchers at the University of Southern California in Los Angeles think the US Army Research Office should consider an alternative – coded smells.
These can be delivered silently, in the dark and when loud noise is drowning out speech. Furthermore, says the USC patent, the immediate reaction to a smell is emotional, rather than rational, so an odour trigger may encourage people to carry out orders without question.
