Base Approach - Bunker Exterior - Part 1

Continue along the path to the north until you come to another ancient truck. Lara ducks as you approach it, indicating there are enemies ahead.

Start with the archer nearest you. Wait until the spotlight is pointing away from him and use your bow to take him out with a headshot.

- OR -

Sneak up on him for a stealth kill. Carefully move up to hide behind the barrels and sandbags ahead near the right wall.

If you make it this far without being detected, you get a nice 100 XP bonus for discovering the location of the bunker.

Then slowly sneak up behind the bad guy. When you see the Melee icon on screen, press it once to get him in a choke hold with your bow.

Then follow the on-screen prompt and repeatedly tap Interact to finish him off.

Loot the body and move up again and crouch behind the wall of sandbags with the arrows leaning against it.
