Chapter 8
Field Maintenance
8-49. Field maintenance returns repaired equipment to Soldiers, provides on-system maintenance, and
mainly involves preventive maintenance and the replacement of defective parts. It covers tasks previously
assigned to operator, crew, organization, unit, and DS maintenance levels. It includes some off-system
maintenance that is critical to mission readiness. Within the BCT, field level maintainers are generally
concentrated in the BSB (FSCs or FMC). Sustainment maintenance consists of repairing components of the
user’s system. It is generally a merging of the previous GS and depot maintenance levels.
Sustainment Maintenance
8-50. Sustainment maintenance is typically performed by an element of the sustainment brigade or higher
echelon (see figure 8-2). The ENCOORD ensures that sustainment maintenance is identified for each
supporting engineer unit. Company commanders ensure that vehicle crews and equipment operators
perform preventive-maintenance checks and services (PMCS).
SUPPLY
Class I
8-51. The various classes of supply are discussed in the following paragraphs.
8-52. Class I supplies consist of subsistence and gratuitous health and welfare items. They are
automatically requested based on daily strength reports. BCT units deploy with three days of operational
rations (meals, ready to eat [MREs]). MREs are distributed in case lots at the BSB distribution point and
picked up by the appropriate supply section (FSC or BSTB). Unitized group rations (UGRs) and A-rations
are broken down into lots at the BSB distribution point and picked up by the appropriate field-feeding
section (FSC or BSTB) for incorporation into the LOGPAC. Water is provided to Soldiers in two forms—
bulk and bottled. Water support is provided through organic water purification and distribution capability
when feasible. Bulk potable water is used as needed for individual Soldiers. Bottled water may be provided
on a limited basis, usually during the deployment phase of operations. Bottled water containers are issued
based on the same unit daily strength reports used for rations and field feeding. The BSB receives, stores,
and distributes water. The BSB may not have adequate equipment to satisfy BCT requirements for water
purification, therefore requiring augmentation. Each company has water trailers and five-gallon containers
for distribution of potable water. Company supply sergeants maintain water trailers in their company area
and refill them from the BSA. The refilling of five-gallon containers typically occurs during LOGPAC
operations.
Class II
8-53. Class II supplies consist of such items as clothing, individual equipment, tenting supplies, hand tools,
administrative and housekeeping supplies, and CBRN defense and decontamination items. Usually, the
BCT deploys with 30 days of common consumable supplies. These supplies are provided by the BSB and
are maintained as part of the BCT authorized stock list. Replenishment and other necessary supplies are
ordered by company supply sergeants using the Property Book Unit Supply-Enhanced (PBUSE) Program
from the BSB. Supplies are provided at the BCT distribution point to the supporting supply unit (FSC or
BSTB) for the appropriate company. They are carried forward with the next LOGPAC or immediately if
needed. Religious supplies and maps are also considered Class II items. Unit ministry teams (UMTs) order
consumable chaplain supplies as necessary. Maps are ordered using the PBUSE Program. Usually, paper
map sheets are delivered with appropriate supplies to the requester.
Class III
8-54. Class III supplies consist of bulk and packaged POL (petroleum fuels, lubricants, hydraulic and
insulating oils, preservatives, liquids and gases, bulk chemical products, coolants, deicer and antifreeze
compounds, components and additives of petroleum and chemical products, coal). The BCT usually
