In the TM Numbering System, which number represents the proponent for the publication?

The first number in the TM (Technical Manual) Numbering System designates the proponent for the publication. This is essential because it identifies the organizational element responsible for the existence and maintenance of the manual. Each technical manual is published to meet a specific need within the Army, and the proponent plays a critical role in ensuring that the content is accurate and up-to-date. By looking at the first number, users can quickly ascertain which agency or command is ultimately responsible for the technical guidance contained within the manual. This helps users understand who to contact for further information or clarifications regarding the manual.

The significance of identifying the proponent through this number also contributes to the overall organization and retrieval of technical documents within the Army's logistical framework, facilitating efficient communication and resource management.
