A Goods Defense

A Goods Defense is a radiant side quest in the Fallout 4 add-on Nuka-World.

Detailed walkthrough
Upon acquiring the quest from either Mason, Nisha, or Mags Black, the player character must travel to the marked location in the Commonwealth, and join a team of gang members sent by the gang leader to guard the place. Upon getting close to the gang crew, a group of attackers will immediately move in to attack, and the player character must then eliminate them, or let the gang do it. Once the area is clear, return to the gang leader for a reward.
