Minecraft wiki entry for Patrol, associated text: Patrols seek villages, wander around, and attack nearby players, adult villagers, iron golems, snow golems‌[Bedrock Edition only] and wandering traders. The patrol members' heads turn to follow a player or villager-like mob who looks at them or attracts their attention. A player or villager-like mob who approaches within 10 blocks of the patrol provokes them into loading their crossbows and attacking, and pursuing if the player flees. The pursuit lasts until either of the parties die or get 10 blocks away.
