FFG has posted information on some more units that will be dropping on battlefields in the near future.
First up, the SSU gets the Hailstorm and Red Lightning Heavy Weapons Teams.

The Hailstorm Heavy Mortar Team (pictured) has a 120mm mortar that can either launch an artillery strike, or an aimed shot at closer range.
Meanwhile, the Red Lightning Tesla Gun Team is armed with a tesla gun, much as you’d expect them to be! The gun can even explode if the unit goes down, dealing damage to nearby units.
The Axis will get more zombies to add to their undead ranks, in the form of the Ubertoten Assault Squad.

These guys are basically the “living undead”, or smart zombies! They come equipped with MG48 guns and the Panzerfaust 100 antitank weapon. The big question doing the rounds at the moment is will they be Infantry 2 or 3? We’ll have to wait to find out.
Finally, the Allies get another heavy walker to add to their ranks with the Heavy Support Walker.

This monster comes in three configurations. The Long Tom II has the Long Tom M2 artillery weapon which, interestingly, doesn’t have to be reloaded, although it’s strictly a long-range weapon.
The Mobile HQ version serves as a Command Vehicle, and allows a squad of 6 to jump inside and command troops. It also comes with three .50 cal MGs.
Finally, the Skysweeper (pictured) is the anti-air variant, and has a triple 60mm anti-air gun for knocking aircraft out of the skies. The gun can also be fired at ground targets.
Unusually, a projected release date isn’t given for these units. But given that the Ubertoten are included, who were revealed as part of the Campaign Book Icarus announcement, it’s probably safe to say they’re part of the Icarus wave scheduled for the first quarter of 2013.
