"Fear not! Their bullets stand no match to-" the Confessor shouted before the missile flew past the man. Well, they meant business that was for sure. You don't bring a missile launcher unless killing is your utmost priority. These weren't assassins oh no. These were people who only thought to kill Kliment. From his distance and with his rosarius he was protected more or less from the blast, but it was the last straw. His aged eyes saw red and there was an indignant jiggling of the chins as he snarled a little. He was about to shout "affix bayonets!" when he remembered he was not with Guardsmen nor PDF, so he had to rethink his course of action a little.

The fizzing of weapons only issued to Grenadiers or Tempestus also made somewhat of an impression on Horacio. For one, if it got past his rosarius (and prayers) he was probably going to be a puddle of sizzling goo. Even he recognized that trying to storm the position was complete and utter suicide so he had to be a little wiser. He hopped out of cover and unloaded his bolt pistol at them whilst keeping himself in full view to hopefully divert their attention before hopping back. After a few moment's wait he ran out but not towards them and took cover on the side of the doorway opposite him. 

Once there he tugged at his shotgun and counted to three he once more hopped out and blasted at the upper torsos of the heretics. From this distance even the blackhammer wouldn't do much damage even to flak unless hitting exposed parts but it would 1) get attention away from his comrades again, 2) demoralize the enemies for a hail of bullets clanking off of your armour is oh so frightening and at last 3) perhaps detonate any grenades they had about their person, though he was not banking on this.
