For those who are not familiar with DBN, here is a great video by Alex Testo - one of the developers, along with Bob Carter. Alex shows all of the different troop types and gives some insight into how they play and other informative bits. I've played DBN since it was first released and I still learned a few things. Plus you get to see some of Alex's great figures. I will add that Alex uses he optional double rank basing, but I prefer the single rank.
