I like having the BEST ARMY. I enjoyed my first game against the Tau. They're an interesting army. They certainly did a good job of moving down my guardsmen. However, they were wiped out when the battle cannon was brought to bear. The lascannon teams took out their Battle suits, which are the only things I've seen them use that are a threat to vehiciles. The flamers worked well on the Kroot and the heavy bolters and autocannon work well against the infantry.
