You are a non-commissioned officer and walking your rounds. You see two men breaking into your building. You should?

As a non-commissioned officer, I would first assess the situation to ensure my safety and that of others nearby. Then, I would contact security or law enforcement to report the break-in while maintaining a safe distance to observe the suspects. If necessary, I would take steps to secure the area and prevent further access until help arrives, all while documenting the incident for future reference.
