1. Purpose: This message is the first in a series guiding the implementation of the Logistics (LG) branch Area of Concentration (AOC) 90A for Second Lieutenants (2LT) and First Lieutenants (1LT).
2. Background.
a.
In 2018, the operational force identified a significant training gap
among junior logistics officers, particularly 2LTs in Transportation
Corps (TC), Ordnance (OD), and Quartermaster (QM). They lacked the
necessary multifunctional logistics skills to make competent decisions
in complex environments. In response, the Army Sustainment University
(ASU) and the Combined Arms Support Command (CASCOM) convened a Critical
Task Site Selection Board. They developed a unified curriculum
integrating TC, OD, and QM knowledge into a cohesive learning strategy.
b.
On 11 January 2023, the Army Sustainment University's Commandant
approved all three Programs of Instruction (POIs)—8-55-C20B, 8-10-C20B,
and 4-9-C20B. Subsequently, the Training and Doctrine Command (TOMA)
validated the aligned course content on 26 June 2024. This strategy
equips Logistics officers to make informed decisions that align with the
objectives set forth by their commanders.
c. On 11 March 2025, the Office of the Deputy Chief of Staff, G1 approved the request to authorize the reclassification of 2LTs and 1LTs to Logistics branch officers (AOC 90A). This decision consolidates the previously separate branches of the TC, OD, and QM into a unified Logistics branch (AOC 90A).
