Figure 13. Field storage distances
e. With the tonnage computed and field storage categories determined, QDs can be determined by using
Table 4-4 of TM 9-1300-206 (see Figure 14, page 18). This table gives the minimum allowable distances
to meet QD requirements when storing ammunition in the field. Using the QD table and depending on
the space available and the terrain, a preliminary determination of FSU and stack placement can be made.
Example 1. Twenty tons of 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. Since these cartridges are high explosive and
not incendiary or chemical, they fall into Category A.
Next, the QD table in Figure 14, page 18 is used. 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 (as in our example), 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 the terrain,
allowable distances, and other items that need to be stored in the ASP.
Example 2. Determine the minimum distance in feet required between Category B and Category D ammunition
(see Figure 14). Category A, B, and D use the same table for field storage. The minimum distance is 750 feet.
Example 3. Determine what distance is required between Categories A and E. Look at the table in Figure
14. Category A requires 750 feet, but Category E requires 900 Feet. The minimum distance required
