Coming back to this topic after a while, I have just finished painting a couple of interesting sets from Zvezda.
The first is British Engineers 1939-42:
Although difficult to assemble, they produce a great group of engineers who could probably be used in a scenario.
The second is British 3 Inch Mortar with Crew 1939-45:
Not quite as tricky to assemble, and they could certainly be used in a scenario because each can be detached from the shared base (I have taken the fourth figure from the base to show this).
Zvezda make very high standard models. The only apparent* fault is that the mortar team is clearly early war (because of the uniform and personal equipment - which is why the engineers are only 1939-42).
