A Gun Emplacement was one of two types of weapon emplacements commonly used in large numbers to defend other above-ground Castle Brian structures and important locations. These emplacements were not built with the same advanced construction techniques as true Brian-class structures, making them easier to construct but not as robust to better serve as disposable defenses. Conditions were cramped inside these emplacements, and they were not meant for long-term habitation. Gun emplacements extended a further level underground, for additional storage and access to tunnels connecting to the rest of the Castle Brian, but could be easily sealed off from the rest of the complex. Their weaponry gave them the firepower of a heavy or assault BattleMech but had overlapping fields of fire and could easily call in artillery fire.[1]
