Could an enemy order a retreat with one of the U.S.'s own radios?
Okay, I know this is an impossibility in real life, but stick with me. Assuming that an enemy knew all of the army's call signs and codes, could they theoretically take a radio from a dead soldier and order a retreat? Or does the army have a way to know where a transmission is coming from and stopping it? Or alternatively would it create mass confusions as both transmissions from base and the radio contradict each other?
