I hightly recommend Guerre Civil/Condor Legion. I playtested some of it and then played more when I finally got the published version in my hands. There is one scenario, it's been a long time I don't remember the title, where both sides have the same tanks. It was quite a tangle to have them fighting each other on a flank. I think they were FT-17s. There are a couple of great geo-morphs and a castle overlay. A couple of the scenarios are Brihuega Disaster, Son Servera, Teruel's Tooth and Ay Carmela. Those are the titles from GC, I'd have to lay all the scenarios out to figure out their new titles in Condor Legion.
