Tales of Valor multiplayer units

Though the list of units hasn't been announced, recent screenshots reveal more of the units players will be able to swap in for multiplayer. These units include the Kangaroo, the Staghound, the M18 Hellcat, the Schwimmwagon, and a Marder I which is based off the French H39 (also in the game as a German unit, upgradeable with what looks to be Walking Stuka launchers). Let the plotting of abuse begin!

Update: They are definitely walking stuka. It is mentioned in this Walking Stuka article.
