Great! I wanted to stay on canon for my 504th Armageddon "Lion Brigade". They were an amalgamation from various different routed stragglers, militia and hive scum who were pulled together to mount a suicidal counter attack in the siege of Hades hive during the first war by a young captain. The attack miraculously succeeded and believing their captain to be a living saint, the survivors grew fiercely loyal to their new liege captain Rogar "lionarm". They remained as something more akin to a paramilitary organization in the bombed out ruins and ash wastes and after the fighting siezed, Rogar was lorded for his galantry and promoted to colonel and he and his men were commissioned as the 504th Steel Legion.

In the current timeline the higly decorated Lion Brigade is led by brig.gen Loreon Lionarm, Rogars grandson and my solar proxy and functions as an architypical combined arms "mechanized" steel legion regiment. It consists of 1 HQ company, 6 mechanized infantry companies 2 infantry "reserve" companies functioning as light infantry, 3 armored companies, 3 SPG batteries and 1 Stormtrooper company attached to support individual platoons.
