1. 2B1 is the storage location.

2. 3C2 is the storage location.

3. Minimum distance that must be maintained between different FSCs of ammunition.

6. Quantity-distance for field storage categories.

a. With tonnage computed and field storage categories resolved, QDs can be determined by using

Table 4-4 of TM 9-1300-206 (see subcourse Figure 7). This table provides the minimum

allowable distances to meet QD requirements for field storage. Using this table, depending on

space available and terrain, a preliminary determination of FSU and stack placement can be

made.

b. The following examples will help familiarize you with the use of Table 4-4.

Example 1. Twenty tons of 1315-C445 (105mm high explosive semifixed artillery cartridges)

are tentatively planned to be stored in one stack. It is necessary for planning to find three things:

the maximum gross tons per stack; the gross tons allowable per FSU; and the minimum

allowable distance between stacks barricaded, stacks unbarricaded, FSU unbarricaded, and

categories.

First, the category of semifixed ammunition must be determined (see Figure 1, page 3). Since

these cartridges are high explosive and not incendiary or chemical, they fall into Category A.

Next, use the table in Figure 7. The Category A section in the extract shows that if a stack of

Category A ammunition is under 10 tons, the top line is used; for 10 tons up to 20 tons (what the

example is), the second line is used. The second line shows the following planning factors:

Twenty tons is the maximum allowable gross tons per stack.

The maximum allowable gross tons per FSU is 400 tons.

The minimum allowable distance between unbarricaded stacks is 50 feet.

The minimum allowable distance between barricaded stacks is 40 feet.

The minimum allowable distance between unbarricaded FSUs is 300 feet.

The minimum allowable distance between categories is 750 feet.

This information can now be used to place stacks and FSUs in a section or in sections, depending

on terrain, allowable distances, and what else needs to be stored.

Example 2. Determine the minimum distance in feet required between Category B and Category

D ammunition. Look at the table in Figure 7. Categories A, B, and D use the same table for

field storage. The minimum distance is 750 feet.

Example 3. Determine how many feet are required between Categories E and A. Look at the

table in Figure 7. Category A requires 750 feet, but Category E requires 900 feet. Minimum

distance is 900 feet because, for safety reasons, the greater distance is always used.
