Initial requirements for which of the following items are not requisitioned because they are automatically distributed to the installation?

The selection of missiles as the correct answer hinges on the operational protocols regarding the distribution of specific munitions. Missiles are considered high-priority items and typically have stringent control measures due to their critical roles in defense operations. Unlike other munitions that may require individual requisitions based on specific operational needs, missiles are often allocated to installations based on a predetermined distribution system that ensures readiness and availability without the need for continuous tracking or requests from the installations.

In contrast, items like bombs, warheads, and fuses may require requisitioning because they are distributed based on specific operational requirements and assessments of current inventory levels. As a result, they do not follow the same automated distribution mechanisms that apply to missiles. This distinction highlights the unique logistical considerations in the management of different types of munitions in military operations.
