In what year was the first NCO manual established?

The first NCO (Non-Commissioned Officer) manual was established in 1917. This year is significant because it marked the formal recognition of the critical role that NCOs play in the structure and functions within the Army. Prior to this point, while NCO duties were acknowledged, there wasn't a comprehensive manual that outlined their responsibilities and expectations.

Establishing a manual in 1917 helped to standardize the training and guidance for NCOs, giving them a framework within which to operate and ensuring they were well-prepared to lead troops and fulfill their roles effectively. This transition was essential, especially as the Army began to grow and modernize during World War I, highlighting the importance of having well-trained NCOs to maintain discipline, efficiency, and effectiveness in military operations.
