  • Gain your mission from Emhi Tchaoryo.
  • Head to any outdoor area in the Valdeaunia Front not under Allied control and make your way to the Stronghold.
    • This is assuming it works like the other bomb drop ops.
  • Check the ??? at the Stronghold. You will plant a bomb.
    • Note: There are two ??? at the Stronghold. Only one will allow you to plant a bomb.
  • Wait for the bomb to explode.
    • The bomb takes approximately 35 game minutes to explode.
  • Click on the ??? again.
  • You will fail the operation under the following conditions:
    • You wait too long to click the ??? after the explosion.
    • You Warp or leave the area before clicking the ??? a second time.
    • You get K.O.'d.
    • A beastman disarms your bomb by getting close to it. Make sure you wait for beastmen platoons to warp out before setting the bomb, or it will be disarmed and you will fail the mission and have to turn it in. (You won't get a message but examining the ??? again will result in a "Nothing out of the ordinary.")
  • Report back to Emhi Tchaoryo to complete the mission.
