[Milsurplus] SINCGARS Radios

[Dick]

Many crypto devices are unclassified when there's no keying material 
(KEYMAT) loaded.  Some, though, are classified even with no KEYMAT loaded. 
Others are Controlled Cryptographic Item (CCI) and require special handling, 
even with no KEYMAT loaded.  You really don't want to have classified or CCI 
in your possession without a valid and current NSA COMSEC account.

Bill, does KYK-13 or KOI-18 ring a bell?

Dick
