"Destroy Bunker" is an objective in the story mission Where Angels Fear to Tread.
Walkthrough[edit]
With Claptrap leading the way, just follow him over to the red barrier. Do not cross through it as it will instantly kill you. Wait for Claptrap to remember you are not a robot so he will open the security gate and let you on through. Go up to the barrier in front of you and wait for the Slab Buzzards to appear. Claptrap runs just after the first explosion.
Once it drops it is back to fighting some. A BUL Loader will deploy just in front of you and Claptrap will run away. Let the Slabs deal with most of the fire so just run forward, to the top of the hill. When you make it there get ready. You have Hyperion Soldiers to contend with, who are armored and likely shielded, in addition to a Constructor. Take them all out. When you do, a door will open to the East. Head through it.
On this road, watch out for the targeting circles. If it is red, stay out of it. Just run along the road upwards for now. Ignore the Loaders, they are much more a distraction than a fight in that concentration. Just keep running along the road. When you approach the next set of cargo containers, cut out to the left and get behind them. Now you have to get through the next part.
The door is guarded by a few Turrets mounted on the wall. From the cover of the cargo containers, fire carefully onto the turrets to minimize the damage you are taking. Enjoy Brick's comment as you blast the second turret and the door opens. You now have numerous WAR Loaders and Soldiers to worry about with a few Repair Surveyors. Defeat all of them and head through the door.
You have made it to the Control Core Supply Depot. Head through and you have more Loaders to deal with. You also have a Constructor attacking and building at you.
Head on up the gentle slope. Brick has sent some Slabs to help you out for now. The problem is the Auto Cannons are shooting them do. Get to the top of the bunker to get at them.

Claptrap: "I will defend you to the death, Minion. OH GOD NO I WON'T!"
Jack: "Oh, you made it past the security wall, huh? That's, ah, that's real cute. Course, the bunker's still going to obliterate ya, but nonetheless - cute."

Brick: "Knock knock, bitches! Open up!"
Through the third gate:
Jack: "Hey, you know how I got my hands on that Vault Key? See, a few years back, Wilhelm and I paid a visit to your little friend Tannis. And we beat her for hours. We ripped it out of her broken fingers. But we let her live. Because that's what heroes do. They show mercy."
Brick: "Slab! You're coimin' up on the bunker. I'm sendin' some of my boys to help ya out!"
Angel: "That forcefield protects the final door to my Chambers. It will only deactivate once you've the bunker."

As you head up the hill:
Brick: "Take out those auto cannons, slab - they're tearin' up your air support."
When you make it to the top of the Bunker:
Handsome Jack: "Alright, fun time is over kiddies - Brick and his mouth-breathers couldn't bust my bunker ... and neither can you."
