The plan was to recreate the original version of Abaddon's First Company with a squad each of elites in black, supported by the usual array of marines in sea green. So one can expect tactical squads etc. in due course.
The first unit (Catulan Reavers) are now complete and the next unit (Justaerin Terminators) are about half way there :-)
Their unit commander or Chieftain:
A couple of Power Fists
5 man Justaerin squad with Multimelta, a couple of combi meltas, a Power Fist and a Chain Fist:
And a sneak preview of what's to follow the Justaerin:
