Product Info

An authentic reproduction of the cipher used by US Army Special Forces (Green Berets) during the Vietnam War and throughout the cold war period.  Designed in conjunction with a Special Forces soldier that actually used the system in the field and who wrote the instruction sheets and a historical record of its use.

At the height of the systems use in South East Asia there were hundreds of singleton Special Forces operators, A-Teams, B-Teams, and communications trans-stations across Vietnam, Laos, and Cambodia all using the DIANA system.  In practice, encrypted messages were sent on high frequency radio channels using morse code which provided an additional level of security.

According to research and firsthand accounts from Special Forces operators this is the last physical cipher wheel used by the U.S. military and has not had much public discussion or exposure until this time.

This cipher is considered unbreakable when used with a One-Time Pad (OTP) per the techniques described. Despite its level of extreme security, the cipher is very easy and fast to use. 

To aid you in quickly using it to encode or decode a message, a worksheet that even a novice can use to create secret messages is included.

Disks are made from wood and all text is deeply laser engraved.  The back of the disk contains the emblem of the US Army Special Forces.  
Made in USA by Creative Crafthouse.
