From the release:
The SSU gains another formidable entry to its ranks today, as the SSU Airborne Walker Transport for Dust Tactics and Dust Warfare is now on sale at your local retailer and on our webstore! This helicopter swoops in fast and drops a KV-47 Walker into the midst of any fray. Launch an attack with speed and power, or bring backup to bear in a timely fashion. The walker has been modified for air transport, and has three optional builds: the Nastasia, the Nikita, and the Nina.
The Nastasia has a long-range gun well suited to blasting foes out of the air. The Nikita can strike hard from afar with a devastating artillery weapon when paired with a spotter squad. The Nina is very effective at laying waste to enemy walkers with its dual RPG-47s.
