Agent Smith calming super soldiers after killing one

Smith flipped the lever with his thumb and fired four shots into Harrison’s chest. The sergeant fell back against the wall and dropped his Bravo. His vest had taken most of it, but he still wheezed out some air.
Smith peered down the sights and squeezed the trigger a few more times. One shot went into Harrison’s throat. The next one tore open his cheek along his jawline. The last three turned his head into a red and ivory mess.
The soldiers had their weapons up. They’d thrown Stealth to the ground and had Smith in their sights. “Do not move,” roared Taylor.
The young agent blew smoke from the pistol’s barrel. “Staff Sergeant Harrison was collaborating with the enemy,” he said. “You all knew that, right?”
“Of course, sir,” said Polk, lowering his weapon.
“I’m only sorry I didn’t shoot the traitor myself,” muttered Taylor.
