Simulator battles are cool, your standard view is basically you looking out of the commanders hatch. There's no armor penetration indicator (which is similar to WoT, only found in arcade battles), no range indication on units so you basically eyeball the distance and fire. There are respawns on simulator mode as well, but they're vehicle specific. Like in the arcade battles you may get 2 to 3 respawns per vehicle.
Got seven kills in one match in my Stug III Ausf. A on "Jungle" map. Oh, and a slight warning: if your cannon breech is damaged, and you fire, there's a chance you blow yourself up. Or it's a bug.
No authentic sights (so far) but I think they're working on it.
