I had installed Invasion44 but its currently uninstalled, my dual core don't have enough power for this, I'm just waiting my overall PC upgrade to reinstall this.
They added new animations, here is the 2.6 release video :
2012 is the WWII year for ArmA2
With
Invasion44 and
Liberation44 you can have the two fronts, west and east, in one game and with the tactical realism of ArmA2 and his goodies (missions editor ... Coop ... mods ... )
