Thanks Peter for the info.
Though born in Eindhoven myself I never heared of this event.
Looking at their pictures:
too many tanks, panzers and modern warfare stuff to my taste. There is enough real wars going on at the moment, why not have a look in Syria, Iraq and Ukraine first?
But the location Eindhoven makes sense because with the technical university and Philips&DAF factories all together the city became a technical centre of The Netherlands and abroad.
