Were Scouts expected to fight an invading force or man anti-aircraft guns?

Ordinary Scouts were mainly expected to observe, scout, and communicate; stories of Scouts manning anti-aircraft guns likely conflate them with cadet or military scouting organizations.

Ordinary Scouts were not primarily intended to serve as a frontline combat force against an invasion. Their useful roles lay in observation, scouting, and communications. Older young people did become involved with anti-aircraft work, but those cases differed from ordinary Scouts and probably involved cadet or military scouting organizations. Youth organizations could support Britain's wider defence system without serving as frontline combat units.
