Step-by-step explanation:
The manual provided in 1829 for training noncommissioned officers (NCOs) was 'Regulations for the Order and Discipline of the Troops of the United States', often referred to as the Blue Book. This influential manual was created by Friedrich Wilhelm von Steuben, a Prussian military officer who served as Inspector General and a Major General of the Continental Army during the American Revolutionary War.
