Which of the following is NOT a type of COMSEC Incident report?

The identification of Mid-Level as not being a recognized type of COMSEC Incident report reflects an understanding of the classifications involved in Communication Security. COMSEC Incident reports are generally categorized into specific types based on the nature of the incident. These types serve to ensure that incidents are properly assessed and addressed, following established protocols.

Technical incidents refer to issues related to the security of cryptographic information systems or equipment malfunctions. Physical Loss incidents pertain to tangible loss of COMSEC materials or equipment, which can jeopardize communications security. Possible Compromise incidents indicate situations where sensitive information may have been exposed or accessed by unauthorized individuals.

Given this structure, it becomes clear that "Mid-Level" does not correspond to an official category of COMSEC Incident report, as no established guidelines classify incidents in this manner in the framework of COMSEC policy. The existence of categories like Technical, Physical Loss, and Possible Compromise illustrates the seriousness and specificity involved in reporting and addressing COMSEC incidents, ensuring that each one is handled according to its unique characteristics and potential impact on security.
