Infernus

The successors to Vulkan's lost pyrophilia.

Infernus or Infernus Squads are a new batch of Primaris Pyromaniacs who grew intensely inspired by the Black Templar Initiates and their Pyreblasters. So now every Primaris Chapter is lugging around a couple of these badboys, which is perfect timing anyways given who has been making their presence known lately.

Overview

Well, treat these guys as your dedicated close-range assault units. These guys are your pyros, so they like to get in close and dirty; making them pretty specialised as a result. They are reserved for large-scale horde clearing and, against Tyranids, are their biggest bane. However, their close-ranged weapons makes them vulnerable to enemy snipers or artillery, and they don't have the cool jetpacks that other close-assault Space Marine units can help mitigate their weaknesses.

Like their Black Templar senpais, almost all of them wield a Pyreblaster as their standard issue. For secondaries, they carry a Bolt Pistol, a combat knife for melee, and frag and krak grenades. All of them wear the standard-issue Mark X: Tacticus Pattern Armour.

Tabletop

On the 10th Edition tabletop, the Inferno bois are equipped with AP0 heavy flamers (or S5 flamers, if you prefer). They also get the ability Purge the Foe, causing one infantry unit that got flamed to make a Battle-Shock test. Got the specialized role of clearing out GEQ units and forcing Battle-Shocks. Still, they're no faster than any other foot soldier and they've only got a 12" non-assault weapon, so transport is often recommended. Remember that Overwatch can now happen in the movement phase, which means your opponent really doesn't want to end a move within 12" of these. Fundamentally the Tacticus version of Flamer Aggressors.
