This mission is located southeast of the Valsa Docks outpost , from a man outside of the shack at the top of the hill. He runs a business, which is to find the dog tags from slain Japanese soldiers and ship their bodies back to their families, for a fee. However, Jason will help him if he promises to give their families a discount. There are three dog tags you need to retrieve from the dead soldiers, however, you aren’t given their exact locations.
When you go to each spot, you are only given the general location and have to find the body. The first one, to the north, has the soldier leaning up against the cannon. The second one, to the west, has the soldier resting up against the wall by the cannon. The last one, towards the south, will have the soldier on the stairs in the underground part of the bunker. You can either use the ladder in the maze-like portion, or go through the opening by the cannon. Bring all three back to get your reward ($500).
