This publication, Army Techniques Publication ATP 4-02.3 Army Health System Support to Maneuver Forces June 2014, is a consolidation of currently existing publications which address Army Health System (AHS) support to maneuver forces. The publications being consolidated into this Army Techniques Publication (ATP) include Field Manual (FM) 4-02.4, FM 4-02.6, and FM 4-02.21. Army Health System resources (personnel and equipment) are organic to a variety of organizations within the brigade combat teams (BCTs). The numbers of personnel, medical equipment, and unit capabilities for providing organic AHS support also varies depending upon the parent formation/organization. It is essential for AHS planners to understand how AHS resources are arrayed across the battlefield and the capabilities and limitations of the various medical assets that are used across the range of military operations in support of the warfighting functions in the conduct of unified land operations and in pursuit of decisive action in any operational environment (OE). To facilitate this understanding, this publication uses the infantry brigade combat team (IBCT) base table of organization and equipment (TOE) for illustrative purposes only. Variances will exist between what is included in this publication and the actual modified TOEs of deployed units. These variances may be due to updates of areas of concentration (AOCs), military occupational specialties (MOSs), and military grades and modifications made to unit's TOE which result in the unit's modified TOE or updates to the base TOEs reflecting Total Army Analysis findings and judgments. Where significant differences exist in the base TOEs of the BCTs, an explanation of these differences is provided. The principle audience for this publication is all commanders and their staffs, command surgeons, AHS planners, and Army Medical Department (AMEDD) personnel and units.
