A Plasma Destroyer, also called a Executioner Plasma Destroyer or Executioner Pattern Plasma Destroyer in some sources, is the largest Plasma Weapon capable of being mounted on the hull of a Leman Russ main battle tank, which creates the variant of that vehicle known as the Leman Russ Executioner. It was also used in ancient times on the Deimos Pattern Predator Executioner by the Space Marine Legions. It is an extremely temperamental weapon that, due to its massive power requirements, is often disliked by Leman Russ Executioner crews for being unable to operate over the course of sustained engagements. However, it has the capability to penetrate most known forms of enemy armour and its extreme destructive potential is the reason that many Imperial Guard commanders try to include at least one Leman Russ Executioner in their armoured formations.
