The battlecruiser is a type of terran capital ship employed in the Koprulu sector. Battlecruisers stem as far back as the early days of the Terran Confederacy in the Koprulu Sector. The Battlecruiser (Commonly abbreviated as BC) is one of the strongest air units in the game and perhaps the strongest unit in the Terran Arsenal. It is armed with various ATS and ATG batteries, missile launch systems, as well as the devastating Yamato Cannon. It is about 1 km in length, and houses about 5000 crew.
