I have been thinking about the communication between team members in the Avengers movies, primarily when they talk over their team radio net. It seems like they have very little radio discipline in the fact that it always seems like they are using each others names. This seems dangerous as there might be people or groups trying to snoop on their radio chatter.
Some of this is fine, for example using "Tony" or "Stark" for Ironman, since his identity is known. Thor is the same, as well as Steve Rogers and War Machine as Colonel Rhodes.
But everyone is always calling Hawkeye "Clint", Black Widow "Nat", or "Romanov", Falcon was called both "Sam" and "Wilson" in Civil War. Again, some of these could be fine, maybe everyone knows who Falcon is, but wouldn't Agents like Black Widow and Hawkeye have better radio discipline drilled into them as super secret agents that sometimes need to go undercover? Isn't that why they have alias names in the first place?
We know they aren't completely careless, since Spiderman is never referred to as "Peter Parker" in Civil War, but Ant Man is called "Lang", which seems bad since his identity is not known very well.
Is there an in-universe explanation for why no one seems to have good radio discipline, or is it just something to make watching the movies easier since the names lead to more natural dialogue?
