TechManual is the second core book in the rebranded Classic BattleTech line. This particular book provides all of the construction rules for tournament-legal units that were presented in Total Warfare. In addition, TechManual introduced the updated Battle Value system—branded "BV 2.0" by fans. TechManual also provides fictional descriptions of the various units that it provides game statistics for, as well as for the weapons and equipment they use, including long-awaited dates of introduction. Similar to Total Warfare, each section of game data is preceded by a fictional introduction, though TechManual's fiction is of a technical nature. Finally, TechManual contains blank record sheets for all the units it covers and tables for the weapons and equipment contained therein.

From the back cover[edit]

How does a MechWarrior interface with a BattleMech? How does a ProtoMech really work? When was the Gauss rifle or the Particle Projector Cannon developed? Or how can I just make my own, cool and unique BattleMech design? If you’ve ever been plagued by these questions, then get on your coveralls and make sure you’ve got your astech certification, because you’re about to dive into BattleTech construction!

A companion volume to Total Warfare, the Classic BattleTech TechManual combines all the construction rules for the various units presented in that core rules set. Streamlined and updated, it contains all the core weaponry and equipment from previous rules set, as well as the newest, bleeding edge technologies. More than just a rulebook, however, the TechManual presents numerous sourcebook-style treatises, providing the in-universe context for these units and the technologies of their development. A must have resource for any BattleTech aficionado!
