DETERMINE AMMUNITION QUANTITY-DISTANCE
AND STORAGE COMPATIBILITY STANDARDS
Critical Task: 03-4020.02-0001
This lesson provides a description of how to specify storage compatibility groups (SCGs) and quantity-
distance (QD) requirements for conventional ammunition.
Terminal Learning Objective
Determine the appropriate SCGs and QD requirements for different types of
You will require only the information contained in this lesson, which includes extracts
from TM 9-1300-206.
You will learn to determine SCGs and QD requirements according to TM 9-1300-206.
The material in this lesson was derived from TM 9-1300-206.
All ammunition and explosives are assigned to an appropriate SCG for storage at Army activities. The
factors that determine these storage compatibility groupings are evaluated on the basis of data
obtained from ammunition drawings, from tests required by TB 700-2, and from other tests performed
during research and development to determine the characteristics of the items.
The highest degree of safety in ammunition and explosive storage could be assured if each item or
division were stored separately. However, such ideal storage is not usually feasible. A proper balance
of safety and other factors frequently requires the mixing of several types of ammunition and explosives
Conventional ammunition comes in many sizes and shapes. Most items have a filler of some type.
Examples of fillers are high explosives (such as TNT and Composition B), chemicals (such as WP and
thermite), and leaflets (for psychological warfare). Some items may have no explosive filler at all. For
example, some types of armor-piercing rounds are made of hardened steel; they are similar to a giant
slug. Ammunition personnel must know which SCG ammunition items belong in, and they must know
which SCGs may be stored together.
Ammunition and explosives may not be stored together with dissimilar materials or with items that
present positive hazards to the munitions. Examples of this are the storage of ammunition and
explosives with flammable or combustible materials, with acids, or with corrosives.
