Have a Market-Garden Army?
If you are putting together a British Para or Airlanding company for a Market-Garden battle (or any force from that period), you'll definitely want to check out "Theirs Is The Glory".
It is a 1946 film cast with British vets that actually fought there. The film utilizes original wartime footage, as well as footage filmed in Arnhem and surrounding areas less than two years after the battle took place! What a great reference for terrain and building modellers.
