The Surreptitious Entry Reference Manual (SERM) is a single document containing over 28,000 pages of information on various locking mechanisms. The purpose of the SERM is to prevent the loss of knowledge pertaining to surreptitious entry tradecraft by identifying those tactics, techniques, procedures, and equipment that have been successfully used in an operational environment. Surreptitious entry tradecraft are those tactics, techniques, procedures, and equipment employed to facilitate an entry and escape observation. Below is a screen capture of the manual.
