If a fault is recorded on a 5988-E with a Circle X, what does it signify?

A fault recorded on a 5988-E with a Circle X signifies that the vehicle is Not Mission Capable (NMC). This designation means that there is a critical issue or a malfunction that prevents the vehicle from performing its designated functions. The Circle X indicates that the problem has been formally logged and needs to be addressed before the vehicle can be considered operational or ready for missions.

Understanding the importance of this designation is crucial for military operations, as an NMC status can affect unit readiness and the ability to fulfill missions. It highlights the necessity for prompt repairs and maintenance to restore the vehicle to a fully operational state.
