From Forge World:
SOLAR AUXILIA FLAMER SECTION
Working in conjunction with Lasrifle Sections, the Solar Auxilia Flamer Section provides close quarters support to their Infantry Tercio. Whether advancing on lightly armoured enemies, assaulting occupied bunkers or entrenched behind Aegis Defence Lines, the gouts of promethium flame from their weapons will drive back foes far greater than them in number. They are also often employed in boarding actions, clearing corridors of ships with ease.
Solar Auxilia Flamer Sections can be deployed as part of an Infantry Tercio in a Solar Auxilia army in Horus Heresy games. Their rules can be found in The Horus Heresy Book Four – Conquest.
This is a complete multi-part resin kit of ten models, including weapon and head options to make a Sergeant.
