What is the purpose of a DD Form 1575 and 1575-1 (brown)?

The purpose of the DD Form 1575 and 1575-1, commonly known as the brown tags, is to identify suspended material in stock. These forms are used to mark items that are not serviceable or are otherwise placed in suspension due to various reasons such as safety concerns, maintenance requirements, or inspection statuses. The brown tags serve as a visual cue that prevents the use of these items until they are cleared for serviceability after proper assessments and repairs, if needed. This process is critical in ensuring that only safe and fully functional equipment is utilized, thus playing an essential role in maintaining standards of safety and operational effectiveness in military operations and aircraft armament systems.

The other options pertain to functions that are not directly related to the purpose of the brown tags. They focus on different aspects of maintenance management and personnel tracking, which are not the primary roles of DD Form 1575 and 1575-1.
