This page is a walkthrough on how to complete the UNSC Distress Call, Courier Squad in Halo Infinite. It’ll navigate you through the necessary steps to freeing the marines.
Begin the Main Mission: Excavation Site
Distress call received from Courier Squad. Rendezvous at their position immediately to provide assistance.
Where to find the Courier Squad
Once you begin the fifth mission, Excavation Site, you’ll gain access to the second island which has multiple distress calls for you to deal with. Courier Squad can be found south of FOB Charlie.
How to Complete Courier Squad
As you arrive you’ll find the Marines which are a part of the Courier Squad trying to fight off several Grunts and Elites. In order to save them you’ll need to clear out the area which can easily be done but keeping your distance and picking enemies off with long range weapons such as a BR75 whilst they’re distracted.
After you’ve dealt with the fist group of enemies, a few Brutes will spawn from pods, so you’ll need to deal with them before this distress call has been completed.
