Defend the JTF Officer is an objective in Pennsylvania Plaza while you have the main objective: Establish Base of Operations in the Division.
Walkthrough[edit]
Advance to the North to close the new gap between the Agent and the Looters who are attacking the JTF forces. There are 3 of them closer to the intersection of W 24th St and 8th Ave
Just a little farther down the road you will have at least 1 more looter to deal with. Eliminate them to complete the optional objective to defend the JTF Officer.
