I worked for a vendor that made networking hardware. On the system there was some flash storage. We sold to the TLAs. When we got kit in for a demo it came back out minus the flash. USB drives and the like are never allowed in a secure area. Best case you get fired, worse case you end up in prison for 100 years. In the case of what they are asking for here, it is likely "hey we have spy in one of the secure areas and we want to copy the data from the floppy on the system (still in use as others have pointed out)." If you got caught with the device you would get shot and it would not matter if they could read what was on the device. Crypto would just slow down what is a time sensitive operation.
