After completing
and talking to some people in the rise of iron "town" area, you will unlock the "Bad Blood" Story mission in the plaguelands. Completing that mission unlocks this strike.
There are some hard jumps, but nothing dangerous in the strike until you reach the boss. You'll come to a shaft with an chained ogre at the bottom. Interacting with it will release it and summon Kovik.
The ogre is invulnerable and has one melee attack. He will generally follow one player around and slam at the that player. His attack can be dodged by jumping. One member of your stirke team should shoot the ogre, and then focus on holding his aggro and dodging.
Kovik has a big gun that will fire nonstop, and can kill players quickly. He also has a melee stomp attack that knocks players back and also inflicts lots of damage. All players should remain in cover, peeking out to shoot Kovik in the head. However, be careful, as Kovik can teleport.
Once you've completed the strike, return to the vanguard scout in the rise of iron "town" area to turn in the quest and get the achievement.
