    Capture the base SAM site (it will also shoot down enemy aircraft for you), then exfil with the armory manifest.

Tips & pitfalls

  • This is one of the hardest areas in Hajin. Go in fully plated with a full squad.
  • The base belongs to Lieutenant Bale. Bale himself spawns at the Re-Education Center in Deadtown, not here.
  • Objective order comes from early player reports. Follow your on-screen markers if they differ.
