The Dragon Roars is a scenario pack that enables players to reenact some key battles from Operation BULLDOG. To facilitate this, the book includes rules on Clan honor and forced withdrawal. It then goes into a historical synopsis of the events leading up to the invasion of the Clan Smoke Jaguar occupation zone. It breaks down the Classic BattleTech action into four waves and provides variants for the Draconis Combine-produced OmniMechs that use Clan-tech weapons. An additional scenario is included for those who wish to use BattleForce 2. The book wraps up with a brief bio of the most important characters.
