I would be surprised if that was true. In the British military you are taught to use full auto in a load of different circumstances. Suppressing fire, breaking contact, clearing rooms, fighting in trenches or other confined/close spaces, all of these are situations where even regular infantry are trained to use full auto with their rifles or carbines. If it is true that the US military tells soldiers never to fire in full auto then that is a waste of a capability of the weapon, like telling somebody that they can only use the long range aperture on their irons and are not allowed to flip to the large aperture.
