From their website:
The first one is Mil Mi-26 – one of the biggest helicopters of the world and the largest one ever to have gone into production. The second one is a medium-size aircraft produced in Poland – PZL W-3 Sokó?. The rules cover three of its versions: unarmed, armed transport and command.
Both of these helicopters are available in Hind Commander battlesets (“Claws of the Bear” and “Shadow of the Eagle”, respectively). Next update is WiP at the moment and will be available soon, so stay tuned!
