Djura must have been "Next Poster", then. Adam followed close behind, fanning to the right and scraping his environs with his eyes, working hard to not activate his semblance out of paranoia. Djura entered the building first, and before Adam could enter, a shriek rang out, followed quickly by the ringing cracks of gunfire. Adam bolted through the door, triggering his semblance a moment before. His mind's eye showed him the three faunus that he would see in just under a second, arrayed on the upper floor of the lobby. He slipped back into reality and began aiming his rifle at where he knew the leftmost faunus would be. Taking cover behind a stone pillar, firing wildly at the desk behind which Djura crouched.

As he finally entered the lobby, Adam was nearly diving forward, halfway into throwing himself behind the desk he had seen, and as he squinted down the crude sights of his rifle, he found his pre-determined aim true. Thanking Fate for earplugs in such a confined space, he squeezed the trigger just as the faunus glanced at the new figure in the lobby, and the room was utterly filled with a cacophonous [i]BANG[/i].

Silently asking for Djura's forgiveness at his very-possibly popped eardrums, he only watched the pillar for long enough to confirm the telltale explosion of stone and paint, followed by the splash of blood and the mad gust of dust-caused wind. Fully into his dive now, Adam dropped his rifle and drew his revolver. He rolled into cover is a manner at least approaching gracefulness, thanking his aura from protecting his head-first landing, and finishing the roll, he shifted his aim to where he 'saw' the rightmost faunus, standing in the open brazenly firing his weapon with newly-increased fear. The much less ear-splitting revolver barked once, then twice, the faunus stumbling back, its head and chest broken beyond repair. Adam caught his breath, knowing that the third faunus would not stand up. Characteristically for amateurs, the faunus was taking cover, waiting for more experienced reinforcements. Unfortunately for Adam, and the proof of the final faunus' inexperience, he had mistaken cover for concealment, and had chosen a thin, decorative, wooden railing. Peeking in the future as he took aim, he saw a miss. Shifting his aim down slightly, he squeezed the revolver's trigger a third time, sending a cone of metal deep into the faunus' brain.

Revulsion hit Adam quickly, only his instincts pulling him to cover and drawing his rifle back into his hands. The first deaths always made him seize up. He desperately wished he were fighting Grimm. 

Deftly reloading his revolver, Adam waited for the rest of the team to catch up, considering the situation under control. For the moment, at least. Adam had learned to not look farther forward than that.
