Which status symbol indicates a deficiency that puts equipment in an inoperative status?

The status symbol indicating a deficiency that results in equipment being classified as inoperative is represented by an "X." This symbol clearly communicates to users and maintainers that there is a problem with the equipment that prevents it from functioning as intended. In operational contexts, such as those encountered by units like the 1st Battalion, 67th Armor Regiment, it is critical to quickly identify and address issues with equipment to ensure mission readiness.

Using the "X" ensures that personnel can easily and effectively recognize which equipment requires immediate attention, making it an important part of equipment management and operational safety. While other symbols may denote different conditions or statuses of equipment, the "X" specifically denotes that the item is not operational due to a deficiency.
