CMS Destruction
As a Radioman, you may very well be involved
with the routine destruction of COMSEC material. The
destruction methods that we discussed earlier are also

details on priority of destruction of CMS materials.
ROUTINE DESTRUCTION.— Superseded
COMSEC material must be destroyed as soon as
possible after supersession. Keying material marked

than 5 days after supersession.
EMERGENCY DESTRUCTION.— COMSEC

divided into three categories:

both precautionary destruction and complete
destruction.
