BattleTech eras

Catalyst Game Labs, the current owners of BattleTech, have divided history into six eras. The products they released are grouped in this manner. Recently newer products have included other distinct time periods by splitting the eras into sub-eras which brings the classification up to nine eras. In addition to those, four more distinct non-canon ones can be identified:[1]
