There are numerous hidden Battlefield 4 dog tags spread throughout the single player campaign that will not only allow you acquire multiple trophies and achievements, but also allow you to use them in your multiplayer profile. They are well hidden, but have no fear as we have discovered each of their locations in Battlefield 4 and will show you where to find each and every one.
Mission 1: Baku
Tag 1: Near the start of the level, when you are approaching the second obstacle to hop over, there will be a door on the right side that you can enter. Do so and the dog tag will be on the wall to the left
Tag 2: After the first large encounter with enemies, you will come to a red room where the squad will hop down to the lower level through the destroyed floor. Before jumping down, enter the room using the rebar wire on the left as a ledge and then jump to the left side of the room over the shelves. The dog tag will be on the left wall there beside the windows. If you happen to fall, not making the jump, you’ll have to start the mission over again to give it another shot.

Tag 17: Just after you reach the dam and take out the helicopter that is buzzing around, you will be told to find a way into the next area.

Hop across to it and then make your way to the rear of the plane and on the left side tail will be the collectible.
