Take them out carefully, don't get careless. Once you take them out. Head through the way to the left. Where you see the laser sight rotating to shoot as being blocked. When Sledge try to ask Strauss how to process as he reply being helpless only you can do it. Just rotate it to the right way where the laser will shoot the door then it will open. Once you enter it, the sentry are waiting for you. Be sure switch to light weapon to dealing with them for saving the ammunition. After taking out, head right.

If it happened and successful kill it. Just head through to the middle. Where the sentry from the below will open the hatch again. Followed the same strategy as you have destroy the first one as you approaching.

The elevator in-front of you will come down as Light Tank are riding it to come get you. Take it out in any of the powerful weapon you have as the hallway of corner are small. Be careful, don't let your team-mate die. Saving is always a good thing especially after you clear the Berserker. Once you take out the Tank, ride that elevator to the top. Where the Gladiator are waiting for you using cover as the corner are limited. After you finish him be sure you recover your health before process. Go through the hallway and head left. There you will see the platform. Where need to be lower after the gunner have block it below. Before you can do it. You must take out the Iron Maiden that quickly spawn after you're in. Douching their rocket are quite tricky as the room are small. Just take your powerful weapon to take them out at once before they finish you.

After taking out, get ready for the light tank coming from the lock door right after you kill both of Maiden. Take him out as soon as possible since the room are very tide. Especially, forcing him using the range weapon against you is a better choice instead of chasing you down. Once you take him out go through it and crouch at the left. Where you can refill your health and armour if you take any damage from the fight moment ago. Head through the stairs as you see the elevator ride to the top. Processing the door twice and you see all the corpses of Cougar Squad as Sledge comment it. Just leave it behind if you are already full. Just processing to the another elevator that take you to the exactly the same location of last tower. There you will be battling the Heavy Hover Tanks with the Gladiators that guarding on top. Make sure, you prepare yourself with the powerful guns you have. Two Tanks can be very tricky as It always flying around to douche your aiming. Nailgun is the best weapon come in to deal with. Also, keep look out of Gladiators as your team-mate taking care and don't let him dead or it will start all over again. Alternatively, if you low on health or supplies, you can avoid fight and just run for the switch before enemies kill Sledge. Once you activated the switch, a transmission from Strauss congrats you and tell Sledge to stay there if the enemy forces want to disable again and he will ask you to go back where you take the elevator come and the level after you activated the switch to go down.

Bugs
There is a bug in this level, when you almost reach to elevator that go to the top. Heading to the third section of the laser. Where the gunner has blocked it. At that part, the Berserker sometimes may not spawn and if it happened, will spawn two or even three times to engaging on you. It is considering to be one of the most annoying part. Where the enemies can easily killed your teammate and ending up with a mission failure, especially other enemies nearby that are distracting you or playing on harder difficulties.
