Wall of Martyrs Vengeance Weapon Battery

A Wall of Martyrs Vengeance Weapon Battery is a heavily-armoured Imperial automated defence unit. Armed with powerful ballistic or directed energy cannons, they unleash deadly salvoes of fire on any enemies that approach them by air or ground.

Countless billions of these batteries have been built over the course of the Imperium of Man's 10,000 Terran year history and they remain a common sight on the battlefields of the 41st Millennium. Each Vengeance Weapon Battery sports a powerful cannon in a rotating turret, which is controlled by a simple automated firing system which will fire on any enemy unit it can sense. The thick plascrete walls of the battery make it invulnerable to all but the most powerful of weapons. Such is their durability that a Vengeance Weapon Battery will often remain operational long after any flesh and blood defenders have been killed or fled the battlefield.

The batteries are usually constructed forward of the main Imperial defence line, where their automated fire can serve as advance warning of an attack while driving the enemy into carefully pre-selected killing zones. They are also often used as automated weapon sentries to protect important locations, freeing up more mobile troops to be used elsewhere.

Vengeance Weapon Batteries are easy to construct and extremely robust, known to operate effectively for hundreds of standard years without requiring maintenance. They are usually armed with either a Battle Cannon, capable of taking on heavily armoured targets, a Punisher Gatling Cannon, capable of scything down entire units of infantry with a single volley, or a quad Icarus Pattern Lascannon, punching aircraft out of the skies with every salvo.
