I think I posted about this blog before - It's an awesome resource for Soviet / Russian armored vehicles. After a long wait, they just updated it with an article on the T-54. Pretty topical since there is a new T-54 series being released. In reading this, I was surprised at how decent the T-54 series was when compared to it's NATO counterparts. Quite a solid, well-designed tank.

I'll probably re-post this on the Russian forum as it's more appropriate over there.
