(This is a subpage of the larger cruise description. In Aalborg, I walked a couple of miles to the Defence and Garrison Museum, housed in a seaplane hangar constructed by the Germans in WWII. It was a small but decent military museum featuring armored vehicles, planes, artillery, and other weapons and vehicles. The highlight for me was a Leopard I tank. A man I talked with told me that Denmark has sent 100 of these to Ukraine. There was also a Centurion and a variety of 1950s era American tanks and APCs. They had a number of exhibits about the Danish army in NATO and I was intrigued to see Soviet invasion plans—revealed by the Poles—that called for numerous nuclear strikes on Denmark, designed to prevent its use as an American shipping center.
