The Desolation Marines were released alongside the Brutalis Dreadnought and the new Primaris
Lieutenant in the Strike Force Agastus boxset earlier in the year, and provide some much longed for Devastator equivalents to the Primaris range, albeit with none of the flexibility. They go somewhat against the grain when it comes to naming convention as you would expect them to be called Desolators but they went with Desolation Squad and Desolation Marine for some reason.
