corps support area to the DSAs. CH-47s task organized to the division and divisional UH-60s
move supplies from the DSA to BSAs and down to the battalion task force level (see Figure 4-1).
Logistics resupply operations are further discussed by class of supply.
Legend: See the glossary for acronyms and abbreviations.
Figure 4-1. Division logistics structure
(1) Class I (subsistence items). Utility helicopters can expect to move large quantities of
class I on the battlefield. CH-47s from the corps medium lift battalion will be used to move
class I supplies from the COSCOM forward to the DSA. Utility helicopters (UH-60s and
CH-47s), operating under division control, will move class I from the DSA forward to the
BSA and, in some instances, as far forward as battalion combat trains. During hot weather
operations, aircraft may move water and ice forward to battalion combat trains. LZs will be
established at DSAs and BSAs specifically for class I.
(2) Class II (organizational clothing/individual equipment). Utility helicopters may find
themselves moving class II on an occasional basis. Replenishing stockage levels of class II
may become a mission for the CH-47s in the corps. These aircraft will move class II
supplies forward from the COSCOM to the DSA. Air movement forward from the DSA will
most likely be accomplished by ground.
(3) Class III (petroleum, oil, and lubricants). Utility and cargo helicopters offer a unique
capability for moving class III. Fuel can be transported rapidly around the battlefield. The
utility and cargo helicopter's function in moving class III is a part of forward arming and
refueling operations.

(a) Forward area refueling equipment or advanced aviation forward area refueling
system. Utility and cargo helicopters can externally transport the FARE system,
AAFARS, and 500-gallon fuel blivets. A complete FARE system is capable of
providing up to six aircraft refueling points, and the AAFARS can provide up to four
refueling points. Air moving a FARP forward allows attack and cavalry aircraft to
rapidly refuel, rearm, and continue the attack or reconnaissance mission. UH aircraft
can also resupply forward FARPs with class V, allowing a full refuel and rearm
capability. Once the FARE system or AAFARS is emplaced, the utility helicopters
can continue to resupply the FARP by externally moving fuel blivets. Once FARP
operations are complete, the utility aircraft are used to extract or reposition the FARP
to a new location. UH-60s can move up to two fuel blivets, while CH-47s can
transport five fuel blivets externally. The use of utility and cargo helicopters to
transport the FARE system offers some advantages, while there are also
disadvantages to this method. Advantages for using utility and cargo aircraft for
transport of the FARE/AAFARS are--
l   Minimum LZ time for the aircraft moving the system.
Ability to transport personnel internally (CH-47 only). The ability to move internal
passengers in the UH-60 may be limited due to the weight of the external loads, particularly
the fuel blivets.
l  
l   Increased flexibility to use aircraft on other missions (no aircraft modification required).
l   Increased flexibility to use backup aircraft if the primary has mechanical difficulties.
l   Ability to jettison the load if the situation dictates.
Disadvantages to using utility and cargo aircraft for transport of the FARE/AAFARS are--
l   Higher flight altitude.
l   Slower speeds.
l   Reduced aircraft maneuverability.
Reduced fuel load (for UH-60s). For the UH-60, it may be necessary to reduce fuel on board
to lift the external loads (fuel blivets). In this case, mission endurance will be decreased.
l  
(b) UH-60/CH-47 forward arming and refueling point operations. UH-60s and
CH-47s can be used for rapid refueling operations for attack and cavalry aircraft. Not
all aircraft can accomplish this mission. CH-47s and UH-60s performing this mission
must have auxiliary fuel tanks. Commanders must decide early if they want to use the
utility and cargo aircraft for this type of FARP so that the appropriate preparation of
the aircraft can be made. Appendix E covers the use of these aircraft to conduct
refueling operations.
(4) Class IV (construction and barrier material). Class IV resupply is a critical mission for
utility helicopters, particularly during a defensive operation. Ground forces preparing for a
defense will use a tremendous amount of class IV, particularly wire. Utility helicopters are
invaluable in moving these supplies forward from the DSA and BSA to task force class IV
