This is diorama
about the battle of Tali-Ihantala, in the isthmus of Karelia,
between Finnish and Soviets, during June-July 1944. The Finnish army
caused heavy losses in the Soviet army, often with panzefausts for
example. The Finnish Stugs destroyed most of the 80 Sviet tanks
against 8 losses!
The Finnish soldiers are converted from Preiser figures, from modern US infantry and German WW2 tank crewmen.
