Someone IM’ed me the answer so at least one person got it.
For those wondering a ‘kick thirteen’ is a KYK-13 encryption loading device. It was replaced by the CYZ-10 (crazy 10).
I liked the KYK-13 better because it was so simple to use, and faster. The CYZ-10 is like a little computer type of thing, and we often had issues with them. They could do more functions but just a general PITA.
You would use these to do things like load COMSEC in a radio.
