The Wall of Martyrs was a series of plastic terrain introduced by Games Workshop in 2012 to represent typical defense emplacements and trench lines that the Imperium would build on various worlds. As a whole, the Wall of Martyrs line is out of print except for occasional rereleases of selected kits. Some kits in this line command relatively high prices on the secondary market.
The collection can be roughly divided into two distinct sets of kits. The Imperial Defense Network line of kits, comprising the Imperial Bunker, Imperial Defense Lines, and Imperial Defense Emplacement tend to be more commonly available due to their 2018 rerelease in Kill Team. The Tempestus Firebase line, comprising the Firestorm Redoubt, Aquilla Strongpoint, and Vengeance Weapons Batteries are much rarer at this point in time.
Update September 2023: The Imperial Defense Network line was once again made available as a limited-time “Made to Order” release, making it even more easily accessible.
The Imperial Defense Network (or defence in British English), was a large kit that combined numerous parts of the Wall of Martyrs into one box. This box contained the following Wall of Martyrs products: 3x Defense Lines, 2x Defense Emplacements, and 1x Bunker. These were the core of the Wall of Martyrs trench network. See below for more on the individual pieces of the network.
The Imperial Bunker kit combines stone walls and steel deck plates to build an imposing center point to a defense network. The sides of the bunker connect seamlessly with Defense Lines or Defense Emplacement kits. The Imperial Bunker kit was also available in a Kill Team product.
The Imperial Defense Line was the core of the trench network and consisted of two long trenches, plus 4 additional small fortifications which can be used to cap off the ends of the trench network or as standalone pieces. The Defense Line kit has been sold on and off over the years and was included in a Kill Team kit in 2018.
The Imperial Defense Emplacement kit provided the pieces necessary to build larger and more intricate trench lines. Each of the 3 larger pieces contained fire ports where troops could fire out from the trench line. The emplacements provided 2- and 3-way junctions to combine with the defense lines to build larger fortifications. The kit also included two standalone fortifications which could be used to cap off the ends of trench lines.
Similar to the Imperial Defense Network box set above, the Tempestus Firebase box combines several other Wall of Martyrs kits into one large set. The Tempestus Firebase contains 1 set of Imperial Defense Emplacements from above, as well as 2x Firestorm Redoubts, 1 Aquilla Strongpoint, and 1 set of Vengeance Weapon Batteries, each of which will be detailed below.
The Firestorm Redoubt is designed to handle anti-aircraft defenses for a Wall of Martyrs emplacement. The redoubt consists of two Icarus pattern quad-linked lascannons atop a sturdy bunker. The gun batteries are interchangeable with those from the Vengeance Weapon Battery kit.
The Aquilla Strongpoint brings titan class weaponry to the Wall of Martyrs. A gargantuan macro cannon sits atop a colossal bunker. Underneath the macro cannon is the strongpoint’s other weapon option–a vortex missile array with seven vortex missiles.
The Vengeance Weapons Battery contains two standalone emplacements whose turrets can be equipped with either battle cannons or punisher cannons. There are two of each weapon included in this kit allowing you to make two battle cannons, two punisher cannons, or one of each. This boxed set is designed to be compatible with the rest of the Wall of Martyrs scenery range, and you can even use the guns from this kit on the Firestorm Redoubt (and vice versa).
A few of the Wall of Martyrs kits were rereleased in 2018 as part of a Kill Team Killzone box. Killzones were designed to provide a complete environment for Kill Team, including a game board, scenery, missions, and special rules. The box included:
