I think it stands for Customer Master Keys, which are something that are used in cloud computing. The contracts that Dynology has been awarded are mostly through the Department of Defense, but the office that's doing the awarding is different. And the one that's in the German contract and is for CMKS is the office that's titled 0409-AQHQ. This is the only contract they've been awarded through this office, and if you search for more information about it, the office itself, you'll find a bunch of contracts for a U.S. regional office in Bavaria. These contracts as Dynology has been awarded are in the field of IT and network, so it makes total sense that they possibly were contracted by a US station in Bavaria to help with a cloud computing issue related to customer master keys, and Millie saw the abbreviation CMKS and assumed that it must be related to the Congressional Knowledge System, because three of the letters are the same.
