Which of the following is NOT a documented symbol on a 5988-E form?

The 5988-E form is a key tool used in Army mechanics and maintenance to document the status of equipment and vehicles. Each symbol on the form has a specific meaning that communicates the equipment's condition or the needs for repair.

The circle O is not one of the standardized symbols included in the documentation for the 5988-E form. Instead, the document uses symbols such as X, which indicates that a deficiency or fault was found, and the dash (–), which shows that no faults were found during the inspection. The data section includes information such as equipment status, description, and any additional remarks.

Understanding the meaning of each symbol is crucial for effective maintenance and communication within Army operations. The other symbols illustrate clear and essential statuses that help personnel address issues promptly, while the circle O does not serve an official purpose on the form, hence is not documented.
