When a soldier forgets an identifying code, what is the remedy they are supposed to use.
I remember a scene from COD MW II where a soldier on the American side is challenged to recite a codeword to identify what side he was on. Sergeant Foley shouted Star. The soldier who was asked said he forgot what to say, and Foley said he should have said Texas. In that context there were plenty of clues for someone, like how they both obviously had American accents, carried American weapons, had an American uniform, and if asked, could easily have recited or done some action or drill or something like that done to American standards just as the Askari proved decades later that they were German soldiers in order to get backpay by doing the proper procedure to handle their service rifles.
Still, I imagine the normal way one is supposed to handle such an issue would be different. It would not be possible to rely on the American soldiers speaking English like a native and the other side would speak virtually no English and certainly not with a native accent in the war in Ukraine where the Ukrainians virtually all know how to speak Russian, both use Warsaw Pact equipment, and are familiar with a lot of Russian media and culture and a decent amount of geography as well.
