The three sub-intelligence disciplines in signal intelligence (SIGINT) are communications intelligence (COMINT), which involves intercepting and analyzing voice and data communications; electronic intelligence (ELINT), which focuses on collecting and interpreting electronic signals emitted by non-communication devices, such as radar; and foreign instrumentation signals intelligence (FISINT), which pertains to the collection of data from foreign weapons systems and technological devices. Together, these disciplines help to gather critical information about adversaries' capabilities and intentions.

SOS is often interpreted as a distress signal, but it does not stand for any specific words. The three letters were chosen for their simplicity and ease of recognition in Morse code: three short signals, three long signals, and three short signals (··· --- ···). It has become universally associated with calls for help, especially in maritime contexts.
