Each Chapter is a fully integrated, developed and very heavily equipped military unit, possessing incredible resources for rapid mobilisation and firepower. This includes a space-faring fleet of battle barges (equivalent to other faction's battleships) and strike cruisers. Compared to the manpower-intensive warships of the Imperial Navy, the Space Marine Fleet's heavily automated vessels are designed particularly for transport and planetary assault, deploying troops via Drop Pods or teleportation (Space Marine Terminators), while their hangars carry numerous craft including space/atmospheric transports (Thunderhawk Gunships and Stormraven Gunships, both of which are also capable of aerial attack), and atmospheric strike craft (Stormhawk Interceptor, Stormtalon Gunship). Space Marines operate a wide range of vehicles, including armoured fighting vehicles (Predator Destructor and Annihilator, Vindicator, Whirlwind) and transports (Rhino, Razorback), most of which have an emphasis on mobility over armour protection (in contrast to the Imperial Guard), although the Marines' Land Raider tank/transport is among the Imperium's best-protected of that type due to its thick all-around armor. Fast attack and recon elements utilise motorbikes and land speeders. A Chapter's main headquarters is its "Fortress-Monastery" which is a citadel located on their homeworld, although some Chapters are fleet-based as they are headquartered on a battle barge instead of a planet. Each Chapter also owns and controls one or more planets from which they draw material resources and recruits.
