Amazon.com Product Description (ISBN 0979204763, Paperback)

General Aleksandr Kerensky and three-quarters of the Star League Defense Force departed human-occupied space more than two hundred and fifty years ago, only to return in 3050 as the Clans: a society dedicated to the highest warrior ideals and bent on conquering the Inner Sphere. With their superior technology and OmniMechs, they almost proved unstoppable, before their defeat at Tukayyid and its fifteen year truce. The year is 3070, and while the Truce of Tukayyid has expired, the Jihad rages. The Inner Sphere 'Mechs hastily upgraded with field modifications to counter the Clans are proving their worth, as notable pilots rise to become heroes and new, more time tested variants-sporting weapons right out of R&D labs-make their presence felt, while the Clan OmniMechs continue to prove they are still the cutting edge of military technology.
Classic BattleTech Technical Readout: 3050 Upgrades fully updates this venerable product, fleshing out the history of each design, including notable MechWarriors/pilots, as well as providing fresh illustrations. Additionally, all the 'Mechs, vehicles and aerospace fighters originally found in the now out-of-print Technical Readout: 2750 are included.
