Don't any of you people actually read manuals??? This is why they publish them, so you can keep up with what's current! Not so you can use an ecclectic mix of whatever you were taught on on TQ3 in 1972 CFB London, combined with nonsense you heard a trucker say on a CB on tv, and junk you made up yourself because "everyone understands it, it's just common sense"!
"Word" has replaced "Roger".
"Sick" is a new pro-word, now closes a conversation, replaces the combination "Roger, I Acknowledge, Out", for expediency purpose.
