This publication provides information on the structure and operation of the division and brigade headquarters medical staff. It is directed toward the surgeons and staff members of the division surgeon's section (DSS) and brigade surgeon's section (BSS). This field manual (FM) outlines the responsibilities of the division and brigade surgeons and their staffs for the heavy conservative divisions (digitized). It provides tactics, techniques, and procedures for directing, controlling, and managing combat health support (CHS) within the division. It describes the interface required of the DSS and BSS, other division elements, and the interface with supporting corps medical elements in accomplishing the CHS mission. It further defines each cell of the DSS and BSS. This manual is the foundation for the continued development and refinement of division CHS doctrinal fundamentals, tactics, techniques, and procedures for Army XXI. In that light, it serves as conceptual "mark on the wall" for thinking about experimenting with and employing new right-sized medical units/elements in the Army XXI light infantry, airborne and air assault divisions, separate brigades, and armored cavalry regiments. This FM is not a stand-alone reference. It is a doctrine publication that speaks to the digitized division and brigade CHS and will require the user to be familiar with FMs 8-10, 8-10-1, 8-10-3, 8-10-4, 8-10-5, 8-10-6, 8-10-7, 8-10-9, 8-42, and 8-55. Users should also be familiar with the coordinating drafts of FMs 63-2-2, 63-20-1, 63-21-1, and 63-23-2.
