Dutch director Jan Fernhout directed, in 1964, a short film entitled "Fortified Switzerland". The 20-minute film presents the Swiss army of the time in full force, with the scenario envisaging an enemy invasion on Swiss soil.
The entire Swiss arsenal of the time is presented in the video. Of course, a lot has changed since then. What has not changed, however, is the will of the Swiss to defend their homeland. The video features historical aircraft and weapons.
