Act 4: The Long Road Home - 1. War Academics

The Longshot is your friend here. Quickly snipe out the many enemies on the other side of the yard. There are quite a few, so be accurate. Also, I just stayed around the starting location through the whole battle. When that side is clear, the side closer to you will be swarmed by Theron Guards and Drones. Take out the rushers first. After that, two Boomers and some guys will appear across from you. Snipe out both Boomers and evade their shots. Then move up and get a read on the two snipers in the building behind the statue, which has probably blocked them from hitting you the whole fight. When all is calm, do not go to where the Boomer burst out of the wall. Collect munitions and go to the building to the right side of the yard for COG #25. Approach the open wall and choose the left path.

Proceed and get the ammo and Frags near the lockers. Up the stairs you should be on alert for a lone Theron who usually rushes. Proceedd to the hole in the wall and take out the two Drones. Then be ready for another wave of enemies to rush your friends: two Therons and one Drone. The Therons have Torquebows so take cover.

When you mantle into the next room, and Seeder will have two Nemacyst in the air - take them out. Go to cover next to the open door and take out the Drones on the ground. When only the Seeder remains, go into the locker room next to you, but be ready for three normal Wretches and one Drone. Swap the Longshot temporarily for the Hammer of Dawn (two in this room) and hide behind the wall to take out the Seeder. Then quickly get a Frag in hand and look for the statue in the middle of the yard (easy to see if you are still in the locker room) and aim a Frag right into it. After this, take out the stragglers.

Pick up the Longshot and keep along the path; there is so ammo behind a tipped over vending machine near a window. Turn the valve and go into the next room for some more ammo.

The next area has some Wretches where you are, some Drones on the ground, and then a lone Sniper on a ledge if you look left of the miracle toilet. Don't forget the ammo near the holy can and then some ammo for the Longshot. Then go downstairs to emerge into a street with two Drones. When you try to cross the road two Wretches pop out of the crack. Don't try to shoot the Troika from behind the fence, just keep going. And snipe the gunner through the window in the next room, and then the other Drone. On the street you are to shoot the propane tanks in the car to open a path.
