Shacknews has posted their preview of Opposing Fronts.
Panzer Elite units are broken into small groups of three or so infantry. Although these groups are weaker in strength than other sides, they also have the advantage of covering more ground, making it much more difficult to defend against them. These infantry can be loaded into vehicles and used as weapon platforms, firing bazookas and rifles from the backseats of halftracks and jeeps. New lieutenant and commander units give troops boosts in ability, although they must be individually managed and kept out of danger, lest they be offed by a sniper.
The much displayed E3 trailer is attached to the end of their post as well. Enjoy!
