Here are four new trailers for Valkyria Chronicles 3, each trailer highlights one of the three groups in the conflict. The East European Imperial Alliance (the bad guys), The Principality of Gallia (The good guys) and in the trailer you see above The Nameless. (The group you will be playing as in VC3)
The fourth trailer details some of the features you will get to use in the nameless barracks such as tank building and weapon modifying.
In my opinion this one looks like the best game in the series yet, far better then Valkyria Chronicles 2 at least.
Hit the Jump for the other three.
The trailer below details the The East European Imperial Alliance.
The trailer below details The Principality of Gallia, including Squad 7.
The final trailer details barracks features.
