I have been trying to trace pow codes from ww2 for yonks . The ones i want are not in Foots history of MI9. i DIGRESS AN SEEING AN PROGRAMME REGARDING THE YANKS ATTEMPTED RESCUE OF POWS IN vIET NAM THEY STATED THAT A LARGE k WAS CODE FOR Come AND GET US , AND THAT OTHER (FECKING CAPLOCKS ) codes were laid out saying x amount of us are wounded . Do the lads who get sent to Afghan get some training in covert communication if captured or on the run ? It seems to me that most of them are stuck right out in the thick of things and are often surrounded by the Talibs .
