Lego, which was founded in 1932 in Denmark, has steadfastly over the years refused to make military toys.
Various entrepreneurs have used original Lego pieces to make various custom kits of tanks and airplanes, but somehow these always fell short in appearance.
Enter in Cobi, a firm from Poland. Apparently, despite the depredations of World War II, Cobi has no issue with offering examples of both well known and lessor known vehicles from the conflict.
I first became aware of their products in, of all places, the gift shop of the National World War I Museum in Kansas City. That is where I spotted the Renault FT-17 that was the subject of my first build.
The advantage of these kits is they will keep your hands busy without the requirements of paint, glue, spray guns, etc. If you are not set up for these things since your youth, it's not a bad alternative.
With that said, you have to be willing to accept the fact that these don't have a super realistic appearance. But if you want something to sit on the book shelf in your library, they can fill the bill. (And they are still much cheaper than buying anything from King and Country!)
