Iron Conflict is a competitive online real-time strategy game coming in Q3 of this year to Steam. This will offer 10v10 online battles with a mix of units spanning different eras from World War II to the present. The chance to experience how this works is on the way, as developer Angela Game promises a beta in the "near future." In the meantime you can get a look at the concept in this Teaser Trailer. Here's a description:

Iron Conflict boasts fan favorites, such as the Type 99 tank and the aforementioned F-35 – along with hundreds of other WWII airplanes and tanks. Map tiles, on the other hand, are randomized – making each battle different from the last. Terrain and buildings can obstruct both lines of sight and lines of fire – creating the opportunity for traps, escape, and exciting games of cat-and-mouse.
