Tier 1: Get The Dead Soldier’s Dog Tags

Fireteam Echo looks like it suffered some casualties.  Pick up the radio and start tracking their locations.  Click on the corpse to collect his dogtags.

Click on the Military Radio in your inventory to start tracking the signal.  The closer you get to the target, the more often it will beep.  With this in mind, head south towards the first map marker.

It will start beeping very quickly as you approach the dock, so take care of the Cold Seep Oracles guarding it.  They will cast a water bubble, make sure to stay out of it.  Other than than, they’re not going to hurt you too badly.

Climb up the boat and get to the front of it on the upper layer.  Kill the Cold Seep Thresher.  Afterwards, click on the dead Fireteam Echo Grenadier’s corpse to collect his dogtags.

Tier 2: Fire-team Echo Dog Tags

Start up the tracking on the Military Radio once again and head to the area indicated on your map.  This time it will lead you to a soldier’s corpse.

Upon examining the corpse, you realize you can’t find it’s dogtags.  You figure that one of the Cold Seep Gorgers must have it.   Start killing the enemies in the area and it will appear on the floor when you kill one.

Tier 3: Kill Shallowskin

The final soldiers corpse has been munched on quite a bit.  When you click on it, Shallowskin will appear and want to take a bite out of you.  Throughout the fight, he will do a self-centered massive AoE that takes up a lot of room and does a lot of damage if you stand in it the entire fight.  Move out of this quickly so as to stay alive as long as possible.

Tier 4: Bring the Dog Tags to Sarge

Once you have the dogtag from Shallowskin, take the bundle of dogtags and bring them to Sarge so that he can do what needs to be done with them.
