Don't Try This At Home exists for a reason: some things are best just left to the professionals. Firemen, policemen, bomb techs, seasoned military veterans even action heroes and superheroes, put their bodies and lives on the line in the course of their job dealing with lots of dangerous stuff. Sometimes the seasoned professional isn't running; maybe they need to stay behind and make a Heroic Sacrifice, or they're just finally letting loose. In these situations, they usually turn to the weaker members of the team and invoke the trope name or something similar.
