Command and Staff
Assistant Commander, Chief of Staff, and Executive Officer
The commander establishes definite responsibilities for assistant
commanders, the chief of staff (COS), and the executive officer
(XO), who at battalion and brigade levels generally functions as the
chief of staff with oversight of the staff. At division level and higher,
there will generally be assistant commanders and a chief of staff. The
commander prescribes the roles, duties, and relationships of the chief
of staff, the staff, and the commanders of subordinate units.
Staff and Chaplain
A military staff is organized to assist the commander with the
accomplishment of the mission. The staff's work permits the unit
commander to focus combat power rapidly and to protect and sustain
the force. The Army chaplain, in addition to being a religious leader,
is a member of the commander's personal staff. The chaplain works
under the immediate control of the commander and has direct access
to the commander. No other officer exercises coordinating staff
responsibility over the chaplain.
Section II Staff Structure
Factors Affecting Staff Organizations
Commanders use their professional knowledge, experience, and
leadership style to organize their individual staffs. Several factors
influence staff organization:
Size and diversity of responsibilities.
Local (distinct) requirements.
Amount of relevant information (RI) each section manages.
Availability, qualifications, and performance of personnel.
