The bunker is a two piece Frontline Wargaming model. I think it's no longer produced but something close can be scratch built.
The German paratroopers are hard plastic Preiser in 1/72nd scale.
The DFS 230 Glider is another Frontline Wargaming model. Only the struts connecting the fuselage to the wings were added as extras.
Also only two additions to the bunker: some barbed wire and a camouflage net. The joint between the two roof top and the walls is not the best but in the end is a nice and big model that portrays well the Belgian forts and that can also be used to the Maginot Line.
