Besides, his current identity was that of a guard, so even if they were manned by an automated system, they wouldn't be able to harm him. Unfortunately, they were being controlled by humans. Those humans heard the explosion and have begun to turn the sentry guns to the center of the explosion. 

Black Mantis had also heard the explosion. He began to panic immediately. He stood up and began pacing about.
