(1) Maintenance is defined as "all action taken to retain materiel in a
serviceable condition or to restore it to serviceability." It includes all supply and repair
actions taken to keep a force in condition to carry out its mission.
(2) The objective of maintenance is to support the combat readiness and
effectiveness of the Army by sustaining weapon systems and equipment in a mission-
ready operational condition as far forward as the situation will permit.
(1) Transportation consists of those services related to the movement of
material and personnel to meet the Army's requirements and commitments. The
successful support of combat operations is dependent upon reliable transportation.
(2) Within the separate brigade, there are several officers who deal
directly with transportation. They must coordinate closely to ensure that transportation
assets are put to optimum use.
(a) The brigade S3 is responsible for planning the operations of
the brigade and recommending operational priorities for transportation to the commander.
(b) The brigade S4 has staff responsibility for transportation and
plans the use of transportation for combat service support.
(3) The traditional transportation functions are mode operations,
movement control, and terminal operations. All three are integrated into an effective
effort to support the combat support and maneuver forces.
(a) Mode Operations.
1 Motor transportation provides the connecting links
between receiving units and major aerial and ocean ports, major supply centers, and rail
and inland waterway terminals. After air, motor transportation is the most flexible mode.
