Which Army pamphlet do unit commanders refer to in order to determine their training ammunition requirements for the upcoming year?

Unit commanders refer to DA PAM 710-2-1 to determine their training ammunition requirements for the upcoming year because this pamphlet specifically outlines the procedures and guidelines for the management of ammunition in units. It provides crucial information on how to assess and calculate ammunition needs based on training requirements, ensuring that units are adequately prepared for their training exercises throughout the year.

In contrast, the other pamphlets serve different purposes: DA PAM 710-2-2 focuses on supply procedures for maintenance and accounting, while DA PAM 710-1 covers supply policy and procedures across the Army. DA PAM 700-24 deals with the logistic aspects of ammunition supply chain management, but it does not directly address the specific training ammunition requirements for unit commanders. Therefore, DA PAM 710-2-1 is the correct resource for commanders to plan their training ammunition effectively.
