There wasn't much to tell with Herold during the various turns this battle had taken. He had wrought a sizeable toll on the enemy, at least compared to what he could do with the somewhat limited ammo he had. Once he realized he only had a dozen slugs left, he decided to switch to his large barrelled autopistol. Unfortunately, it would still take multiple shots from the weapon to down a full sized Orkoid unless he got lucky with a shot to the eye or temple, but it was all he cared to afford at the moment. 

Once the Grots had their green gas tossed at them, he placed his rebreather on within moments, very glad he had it issued to him before he'd been enlisted in this outfit. Of course, the rebreather didn't prepare him for any of the Emperor cursed twists that came at them moments later, with the igniting of the gas and the multiple rockets traded between the now crumbling bunker and the Xenos brutes that still somehow bore down on them from outside. 

Not to be intimidated out of giving aid to an Adeptus Astartes, Herold gave a gruff nod in return to Nergüi's proclamation he was bringing the fight to the enemy. "I'm with you." The Arbites said, free hand gripping his shield in anticipation. It was mere seconds later that the Death Watch Astartes vaulted over the rubble. Herold followed him, albeit at a slower and less overt pace. Instead he inexorably advanced, shield hefted in front of his body as his autopistol picked apart any Gretchin or Ork that stood in his way. 

It wasn't long that he heard the tell-tale 'click' of his autopistol running out of ammo, and he holstered it as a nasty Ork charged him. Luckily, Herold was quick enough to whip out his Power Maul, the power revved up to maximum. Even bumping a normal human could rip off limbs when this weapon was charged at full power, and though Orks were far tougher than a man, it was still a flesh and blood creature, and when Herold took it by the knee, its knee caved all the same. Herold finished it off by crushing its head with the Maul. Suddenly, more shoota bullets ricocheted off his shield, and he was glad he kept it hefted. There was too many of them still, by the Emperor!
