They can look for anything strange and then either deal with it or come back to report to him. He can also switch places with them when convenient.

Back in the army, patrols were sent out, even though the commanding officer obviously couldn't see what the patrols could see. The patrolling soldiers were assumed to react appropriately when noticing anything strange or alarming.
