The stronghold is the basis of Squat civilization. A planet may have several strongholds, but rarely more than half a dozen. The warriors from a stronghold are its Brotherhoods, so called because of their close blood relationship and ties of vengeance rights. Strongholds sometimes band together into leagues.
The leader of the stronghold is called the Lord. The leaders of the stronghold's Brotherhoods are called Warlords, and they are usually close relations of the Lord. In battle each Warlord leads a Brotherhood as well as his own personal Hearthguard.
The Squats use many armoured vehicles, fast Guild Bikes, and flying machines on the battlefield. They use fast, heavily armed Gyrocopters for scouting and making flanking and hit and run attacks. The sight of a Guild Bike squadron roaring down on the enemy has been known to break the enemy's resolve and create panic among the enemy troops, such is their reputation.
