Secure the prisoner(s) (of war); search them (for weapons, equipment, documents, etc.); keep them silent (so they can’t cook up stories and make plans of escape or assault), segregate them (genereally, seperate the officers from the NCOs from the lower enlisted—break up their chain of command), “speed” them to the rear area for processing and interrogation.
POWs get to keep their helmets while at the front until they reach the rear for their personal protection. Maybe a water bottle, too. But the whole process is meant to break down their ability, unity, and will to fight and send them to the rear areas as soon as possible so any info gained is as current as possible.
Thanks. I’m an old Airborne grunt circa Iran Hostage so I knew all of that. I was mainly poking fun @ sandrat because he repeated his misspelling in his reply to the OP in 13. Glad you cleared it up for others! I was too busy getting my jollies.
