I had never checked 1/48th figures before. Most people, myself included, seem to build 1/35th. Seems 48th isn't a good scale for Dioramas given the limited number of figure sets. tamiya do a few, but only one that could fit your scene.

main problem with this is that the Infantry are all SS. But some of the vehicle crew could be ok, though they are late war.
