Chapter 2: Halvo Bay Military Academy
COG TAG 9: ENFIELD BRIDGE
When you reach the bridge with the Reavers, the tag will be on the center bridge, to the left side, just over halfway down.
COG TAG 10: COURTYARD
When you enter the Institute of Science and Technology through the doors that the Rager locust comes out of, clear the room and then head for the small office on the left side. On the floor in front of the desk will be the tag.
COG TAG 11: R&D LABS
Once you clear the fight in gas filled room (if you accepted the Declassify), you will then enter a room to the right, off the main room. When you enter this room, go to the far right, and in the left side corner will be the tag on the ground.
COG TAG 12: MONROE COMMONS
When you enter the first large area with Jack….er…with the bot, there will be two rooms on the right side; 22 and 24. Enter room 24 and behind the large desk across from the door will be the tag on the ground.
COG TAG 13: ATRIUM
At the start of this mission, you will need to clear out a room of Locusts with only pistols (if you chose Declassify). Once the room is clear, enter the smaller room on the right side and the tags will be on the floor in the center of the room.
COG TAG 14: CRASH SITE
As soon as the mission starts, turn and walk up the small stairs that have blood stains on them. Turn to the right and the tags will be on the ground near the corner.
