One scenario Sgt Rock is talking about available here is Flaming Sword of Vengeance.
*But* -I know the author of this had written on the Blitz's board- this same topic- there is an updated version of that scenario there -the one here seems to be the original by that author (and to me seemed unfinished- unit portraits not matching up, typographical errors on strengths [e.g. -Marders with a defense strength of 46 (whereas Tiger Is are 23)- among others.
I was working on fixing this until I found FSRGold - but even that seems to have some issues, that I wanted to play around with. One thing is that the morale rates for regular Soviets seem about 1 point too low. In a typical Soviet (non Guards) infantry division - 2 regiments have starting morales of D and one rgt has a starting morale of E - that seemed a little too low for me for January 1943 -so I went in and edited these up to 2 rgts's with C morale and one with D -and even that might be a little too arbitrary- and the D might be a little too low.
Anyway, I am playing around with that particular scenario (and it is a huge one-- 421 turns on I think the entire campaign map -maybe more- as it goes to Dnepropetrovosk -and I don't remember the Kharkov map itself extending that far...

I wonder if Cassino is an option - particularly if you can mate it to Anzio. Otoh I would prefer earlier war situations -aside from that I hope the next title is a Western Front or Med Front title. That's just me though.
