Sustainment Support for Engineer Operations
deploys with half-full vehicle fuel tanks, purged fuelers, and empty fuel cans. Fuel is issued upon BCT
arrival in the theater. Units forecast requirements based on the current or upcoming mission. The forecast is
SOP-dependent, but is usually for the 72-hour period beyond the next day or up to 96 hours. The BSB fuel
and water support platoon transports fuel to FSCs for maneuver battalions or the BSTB support platoon.
Class IV
8-55. Class IV supplies consist of construction materials, including fortification and barrier materials.
These are items for which allowances are not prescribed. The management of Class IV supplies for
survivability is most efficient when there is a shared interest between maneuvers and engineer logisticians.
BCT units deploy with a limited amount of Class IV barrier material, primarily for the protection of unit
perimeters and key positions. This material is considered the unit basic load (UBL), and is usually carried
on tactical vehicles. Replenishment is ordered by company supply sergeants using the PBUSE Program
from the BSB. Supplies are provided from the BCT distribution point and carried forward by sustainment
elements with the next LOGPAC or immediately if necessary. Barrier material may also be requested as
configured loads. The ENCOORD typically coordinates closely with the logistics staff to assist in
managing barrier and construction materials. (See FM 3-90.6 for additional information.)
Class V
8-56. Class V supplies consist of all types of ammunition (chemical, radiological, and special weapons;
bombs; explosives; mines; fuses; detonators; pyrotechnics; missiles; rockets; propellants). Class V supplies
are based on a required supply rate (RSR) or controlled supply rate (CSR). RSR is the amount of
ammunition, usually expressed in rounds-per-weapon per day, estimated to be required to sustain
operations, without restriction, for a specific period. The BCT S-3 develops the RSR. CSR is the rate of
ammunition consumption that can be supported (considering availability, facilities, and transportation) for
a given period. The CSR may be less than the RSR. If the RSR exceeds the CSR, the commander
determines who receives the ammunition. A combat load is the unit commander’s designated quantity of
munitions and items authorized to be carried by unit personnel and combat vehicles (turret load). Troopcarried
munitions to accompany troops (TAT) are those issued before departure from the aerial port of
embarkation (APOE). Turret load or combat load munitions are those authorized for transportation in
thick-skinned vehicles for deployment purposes. Generally, BCTs try to keep three combat loads of critical
munitions on hand. Most units do not deploy with their authorized basic load (ABL) of ammunition.
Instead, they are issued their combat load upon arrival in the theater. However, there are times when
selected units deploy with a full combat load of ammunition.
Class VI
8-57. Class VI supplies consist of all personal-demand items (candy, cigarettes, soap, cameras [nonmilitary
sale items]). BCT Soldiers are usually directed to deploy with 30 days of personal comfort items. Health
and comfort packages (HCPs) are also Class VI items. Class VI support is obtained through supply
channels when a post exchange (PX) is not available. Resupply flow is the same as for Class I supplies.
The delivery of HCPs is based on the head count provided for field feeding.
Class VII
8-58. Class VII supplies consist of major end items (launchers, tanks, mobile machine shops, vehicles,
organizational tool sets). Units deploy with all required equipment based on the appropriate MTOE.
Additional equipment may be issued to the unit in theater based on mission requirements. Class VII
replacement is based on losses reported through command channels. Reporting the loss of major end items
permits the commander to remain apprised of the operational status of subordinate commands and to direct
the distribution of items to those units having the most critical need. Replacement Class VII equipment is
delivered to the BSA BCT.
