Kind of skimpy, very little art or maps or anything like that, and they got some really basic facts wrong. CNT wasn't a communist designation! it was the largest anarchist trade union. The Socialist union was the UGT, which was also a slogan used alot on vehicles. They covered armored vehicles but forgot about camiones blindados (“tiznaos”), the armored trucks which were used both as tanks and APC's. They also left out the dynamiteros from the various troop types, and I didn't see much if anything about German or Italian volunteers. Also they had political militias in the Basque countries, not just Basque nationalists. There were also a lot more elite columns other than the two they mentioned.
