Might want to ask yourself where you learned that, then discount that source as a valid source of information in the future.

Video games is where I “learned” it. Outfit a gun in, say, Call of Duty or Rainbow Six. Highlight whatever the particular game calls a “flash suppressor”. I’ll bet it says something like “hides your location from other players when fired”, or something like that.

Which of course is not what a flash suppressor does at all.
