Wehrhafte Schweiz is a Swiss Army propaganda film, made for the Expo 64 national exhibition in the then-prevailing spirit of geistige Landesverteidigung, "cultural national defense". It portrays the Swiss Army fighting against an unnamed, unseen enemy, using heavy weapons such as flamethrowers, artillery, tanks and bomber aircraft. After the enemy is repelled, the film closes with idyllic shots of beautiful Swiss landscapes. The 20-minute film was shot using the latest action film techniques in the Cinerama format on expensive MCS-70 Super Panorama 70mm stock. (Wikipedia)
