Varga's Drop Legion
They were usually beamed into the midst of battles using the giant tellyportas mounted on the Roks in orbit, disorienting the Imperials who were fighting them. Often however the tellyportas didn't work correctly, and Orks would appear on the wrong side of the planet, or miles up in the sky. This made it an unpopular method of transport, but it was very effective when it worked. They are generally formed of boyz and Nobz who the Warboss doesn't like much.
