well maybe you got a table to translate the incoming message, but you only have the option of four responses, depending on the mission, if its a deep recon mission you might just go to your radio and press the word WMD, and then the radio automatically transmits the morse code signal and then the incoming message from hq is sent to you and you either translate it, or it pops up on the screen what the message is saying like you're some kind of veteran and know morse code by heart. You might do the second idea for the latter missions and the first idea for the first mission.
