the combat troops being supported. Storage sites should be located close to the main supply route
(MSR) and supported units to allow easy access. The distance to supported units will be minimized
within security constraints.
ASPs are in the Corps forward area. They provide direct support to the combat division, or portions of
the division. ASPs must store approximately a one- to three-day supply of ammunition to meet routine,
surge, and emergency requirements for supported units. The tonnage stored varies depending upon the
types of units supported. Based on their mission, forward ASPs are usually temporary. This means
ammunition is not stored in a permanent ammunition storage facility.
ASP sites are preferably arranged into three storage sections in order to provide dispersion. This
arrangement also expedites the handling, receipt, and issue of materiel, and facilitates inventory and
segregation. Operation in each section should be rotated daily, if practical. Each section should be
capable of storing approximately 500 tons of explosives and ammunition.
PART A- FIELD STORAGE CATEGORIES
1. Safe field storage often becomes difficult because the amount of land available is restricted, or
components of complete rounds have to be stored in stacks adjacent to each other. Thus, field storage
categories were developed to make it easier to render speedy, yet safe service to units that the ASP will
2. Field storage categories (FSC).
(1) Storage categories are the principal groups into which Class V materiel is segregated for
storage in a field environment.
(2) These groups are based on the following considerations:
(a) Desirability of storing components of complete rounds (separate loading) in adjacent
stacks (complete round concept).
(b) Hazards involved with the munition, such as propagation of explosion, range of
(3) Items having comparable storage risks are grouped together in the same category.
(4) Quantity per storage location by category (stack and field storage unit) is based on gross
weight, with the exception of net explosive weight (NEW) for modular storage.
(5) There are seven storage categories (A thru G) for conventional ammunition.
(6) Small arms cartridges (except bulk-packed tracer and incendiary) may be stored with any
field storage category.
b. Identification of types of ammunition assigned to each category.
(1) Calibers/sizes within each category.
