ammunition and the terrain of the ASP (Figure 5). Each FSU should store only one field storage
category. This makes the computation of QD much easier, and greatly enhances the safety of stored
NOTE: Look at the ASP map below. This ASP layout has 3 sections, 10 FSUs, and 30 stacks (in the
map, every storage location is a stack.)
Figure 5. Example of an ASP layout showing storage location codes
All the stacks of a section begin with the number of the section.
Storage locations (such as 1A1, 1A2, and 1A3 in Section 1) represent one FSU, because they are
all in Section 1 and FSU A, and three different stacks.
It takes at least 2 stacks to make an FSU.
2. Determining quantity-distance requirements: Quantity-Distance (QD) is the minimum distance that
must be maintained between different FSCs of ammunition. QD also is the minimum distance
between ammunition storage sites and other work areas, inhabited areas, roadways, and any area that
could be damaged by fire or explosion. QDs are measurements between stored munitions in an ASP.
The more hazardous the ammunition, the farther away it must be separated.

to minimize their loss due to fire, accidental explosion, and enemy action.
b. Each type of ammunition should be stored in a minimum of two widely separated FSUs to
prevent the loss of contents of any one FSU from seriously handicapping military operations by
loss of the entire supply of any item.
