Emergency destruction. The commander selects emergency destruction for a facility. His decision is
based on a comprehensive threat assessment, the facility's condition, and available destruction facilities. The
three major areas of interest in emergency destruction are the priorities, the methods, and the destruction records.
a. There are nine priorities of cryptomaterial destruction. These priorities are listed in descending order
of importance.
(1) Superseded and current classified keying material marked CRYPTO. These are given the highest
destruction priority.
(2) Superseded, current, and future card reader insert boards (CRIB).
(3) TOP SECRET multiholder key that becomes effective within the next 30 days.
(4) Superseded tactical operations codes.
(5) SECRET and CONFIDENTIAL multiholder key that becomes effective within the next 30 days.
(6) Sensitive pages of crypto equipment manuals or the complete manual.
(7) CLASSIFIED elements or subassemblies of COMSEC equipment in the order listed in the
maintenance manuals.
(8) The balance of COMSEC equipment maintenance manuals and classified operating instructions.
(9) Any remaining classified COMSEC material and unclassified keying material marked CRYPTO.
Superseded authenticators and unused two-copy (point-to-point) key are destroyed if time permits.
b. Destruction must render COMSEC equipment unusable and nonrepairable. The means and methods
to do this vary, depending on what is being destroyed.
