So this go around, it's the 4th Company, one of the Battle Line Companies.  This is one of the more active companies, constantly patrolling for any threats to their sphere of influence.  After this post, there is still the 5th Company (Battle Company), 6th Company (Reserve Tactical Company), and 8th Company (Reserve Assault Company) left to post still.
 
4th Company, Battle Company "Lion's Claws"
    The 4th Company, like 2nd Company, is tasked with actively patrolling the areas around Cymru.  In addition to pursuing alien and heretic forces, they also bolster and augment the defenses of allied systems.
