Virtual Interior: The entire interior of the tanks is modeled, with useable hatches, periscopes, viewports, etc. The driver, hull mg, and commander can all unbutton their hatches. (Source: RPS Interview Yoshiro)Tank Locking: Tank commanders can choose to lock their tanks or allow other players to join their crew. (Source: RPS Interview)
New Tank Damage System: Heroes of Stalingrad has a significantly more complex damage system than Ostfront. Damage to systems such as optics, engine, transmission, turret rotation mechanism, fuel tank, drive sprocket, treads and more are modelled. Shots that penetrate the tank's armor can kill crewmembers inside. Crewmembers have individual hitboxes within the tank and are killable via penetration of an AT rifle round.

Tank Crew (AI/Human): All tanks will have a full crew; any playable positions that are not filled by a human player will be filled by AI. The AI can be ordered to drive, or open fire on specified targets as commanded by the player. (Source: RPS Interview - GDC11 Presentation)
Dynamic tank class system: There will be one tank commander class slot for each tank; as commanders choose to allow human players in their tanks, tank crew class slots will dynamically open up. This means that players don't have to make a choice between having more tanks with solo tanking or fewer with team tanking. (Source: Ramm-Jaeger)
Realistic Modelled Tank Destruction: Tanks can be destroyed by secondary explosions, caused by diffirent circumstances. Fuel fires, ammo blowing up etc. (Source: Wilsonam)
