It's hard for anyone to imagine one of House Umber's famous berserkers fighting on horseback; However, a few of them have been trained in the equestrian arts until they become raiders, troops as fast and deadly as any other cavalry unit in Westeros. Now, what differentiates them from the traditional knights of the South is that they do not wear armor as thick as theirs, but they move with the same speed and attack with the same toughness. Allowing a formation of raiders to attack your flank or rear is an invitation to a quick and cruel death, so a good commander will position them so that they are always ready to carry out a charge as glorious as it is devastating, although he must take care who do not engage in prolonged hand-to-hand combat.
