Red Dawn is fiction.
The fundamentals it respects are real, and they can be learned.
Eight lessons run through the film.
Community Comes First
The Wolverines survive because they depend on each other and on neighbors like the Masons.
Know Your Rights And Your History
The film opens on a country where freedoms have vanished. Study how they were won.
Understand Records
Form 4473 is the firearms transaction record. In the film, the occupiers use those records to find gun owners.
Master Your Tools
Marksmanship, safe handling and good judgment are skills, and skills need training.
Prepare And Be Self-Reliant
Food, water, shelter, first aid and a plan keep a group going when systems fail.
Know The Terrain
The Wolverines win because they know the land better than the invaders do.
