Pyotr didn't need to be told twice to do his job. From his vantage point atop Varvara, he began to do his bit: looking for targets armed with proper weaponry, lining them up in his iron sights, and taking them out with a bullet to the chest. Relatively efficient, and despite what some might think, a far more viable target than shooting them in the head just because they were more likely to take the hit at all.
Five rounds fired later, and Varvara was starting to be targeted with masonry, so Pyotr spurred her a little ways down the barrier, just quickly enough to become a difficult target for the time she was moving, giving him the moments needed to reload his weapon. He couldn't allow her to be injured, not in this situation, and nor could he allowed his teammates to take damage, thus his intent to fire at the most dangerous rioters, the ones actually armed with weapons. Woe that he couldn't target the weapons themselves, but no gun was that accurate, nor any hand so steady.
