Is there any documentation, guidance or general orders on aligning education with doctrinal changes? I'm especially interested as an outsider viewing the military on how changes in basic expectations are pushed through the military education system. What if any planning is done to insure that those who have already passed through a portal of education are re-trained on substantive changes in expectations?

Consider the scenario that a soldier is given NBC training (I know it is now called CBRN in some places). When that training is delivered doctrine might suggest blowing an agent in place as a method of destruction. Then it pointed out that this is woefully incorrect as it can disperse a chemical agent rather than fully destroy it.

Willingly not looking at specifics how would such a change be pushed through quickly? Can it it be done quickly?
