Here's a little action diorama by Darkbird based on Italeri's (now discontinued?) 1/72 SiS/ZiS 3 76mm anti-tank gun featured on the Armourfast forum. I like vignettes and I think this one is very nice indeed, it really captures a moment in time with the help of some good photography.
The model of the gun itself has been very nicely done and as I am about to start working on Soviet artillery after my current batch of Soviet tanks it's given me some much needed inspiration.
