A picture is worth a thousand words. Do as I say, not as I do. It's important for you but leaders are immortal, so live with it.
All those guys not wearing giant kapok vests are leaders. You can tell from their yellow and white hats how floatable they are even without life jackets. Important people float by their own sense of importance even if they are swept overboard.
As an antique fire control officer, I laugh at the train/warning circle around mount 51 and the complete lack of a blast warning zone around the vertical launch cells. OP-4 must be a very weird read these days.
