Field Storage Categories
Field storage categories are the compatibility groupings used for ammunition storage in the field.
These
categories are as follows:
Category A: Fixed and semifixed ammunition (except chemical and incendiary).
Category B: Separate-loading artillery projectiles, propelling charges, primers, and flash reducers (except
chemical and incendiary).
Category C: Mortar ammunition and hand grenades (except chemical and incendiary).
Category D: All pyrotechnics, and chemical and incendiary ammunition of all types.
Category E: All demolition explosives, antitank (AT) and antipersonnel (APERS) mines (except VX-loaded),
blasting caps, firing devices, detonating cords, and safety fuses.
Category F: Rockets, rocket motors, guided missiles, and rifle grenades (except chemical).
Category G: Unfused high-explosive (HE) bombs, aircraft mines, aircraft torpedoes, fragmentation bombs,
cluster bombs, fuzes, primers, and detonators.
Quantity-Distance Requirements
Three kinds of distance are used in determining the QD requirements for a storage section. These are the
interstack, inter-FSU, and intercategory distances. These distances are illustrated in Figure 3.
