Leveraging Sustainment Organizations in CONUS - 
LSOC authorizes Active Component (AC) Expeditionary Sustainment Commands (ESCs) in CONUS to support Senior Commanders (SCs), installation Mission Support Elements (MSEs), sustainment organizations, and sustainment staff officers efforts to resolve mentorship, training, and materiel management shortfalls in these formations caused by repeated deployments and the complexities of the Echelons Above Brigade (EAB) ARFORGEN process.

LSOC does not change existing Command and Control (C2) or Training and Readiness Authority (TRA) relationships; rather, it provides the two AC ESCs with coordinating authority.
