This is first volume in a series of Technical Readout by Era, which is designed as an introductory companion volume to go with the BattleMech Manual, and thus primarily addressing new players, Technical Readout: Succession Wars is a compilation of 'Mech designs from Technical Readout: 3039, Technical Readout: 3050 Upgrade, Technical Readout: 3058 Upgrade, and Technical Readout: 3075 with a selection of designs stretching from the Age of War to the cusp of Clan Invasion in a single book.

While most of the book's content is taken verbatim from Technical Readout products that preceded it, a small number of new art pieces and entirely new variants are included. Conversely, a few 'Mech designs were omitted because of (new) unseen concerns even though some of these (including namely the Stinger, Wasp, Phoenix Hawk, Rifleman, Archer, Warhammer, Marauder, and Longbow) were extremely common to the point of being iconic in the Succession Wars timeframe.

The book was start point of reorganizing Technical Readouts by Era verse by Year in attempt to make the series more new user friendly.
