Military History channel

I didn’t see a tv forum so I’ll ask here. How many of you guys watch Military History channel or American Heroes Channel? I’m trying to remember an interview with a Canadian soldier on a WWII show I saw recently. He was recalling a time during the war when he and his men were heading back to their platoon. The soldiers they were approaching were American IIRC. They yelled “what’s the password” and he shouted the password, I can’t remember what he said though. This has been driving me nuts for three days now!!! It was the wrong password as it had been changed. I think he said the new password was Tobruk. Anybody care to save my sanity????
