Detailed walkthrough
The main objective of the "The Guns of Anchorage" is to destroy a set of three artillery guns.

Like all quests in this add-on, it is very linear. Be aware though that there are a total of 10 intel suitcases to be found in the 3 quests inside the simulator and that you need to find all of them to gain the Covert Ops perk. These suitcases are usually slightly off the path or behind (very easy or easy) locked doors.

Infiltrate the Chinese artillery site
You start off at the Anchorage Cliffs with Sergeant Benjamin Montgomery waking you up. You are part of a U.S. paratrooper infiltration team, and your objective is to take out the artillery guns located here. To do this, you should first infiltrate the Chinese Artillery Outpost and meet him there. Montgomery then proceeds to climb up the cliffs.

Lacking his climbing abilities, you have to take the long way. Follow the path to the right, and you'll encounter a Chinese soldier. These communists are equipped with hard-hitting Chinese assault rifles, but their winterized Chinese jumpsuits have very low DR. You'll follow a winding catwalk around the exterior of a building, and, once at the top, take a right to find a health dispenser, a frag mine, and a sniper rifle. Head through a small building, and you'll be able to replenish your ammunition, and pick up some more explosives and a Chinese assault rifle. Fighting more Chinese soldiers along the way, keep following the path, if you walk up the broken bridge you will find a Stealth Boy sitting on top of some boxes, now head over the pipes until you reach the Cave outpost.

Meet Sergeant Montgomery
Inside the cavern, a shootout will occur between several more Chinese soldiers and an American paratrooper. His Gauss rifle is hardly useful in close-quarters, and the Reds will drop him quickly. It will, however, prove a useful tool for long-ranges, so long as you find some microfusion cells. A hidden room to the southeast has some, as well as other supplies. In a room upstairs, Montgomery drops from the ceiling and rejoins you. During the conversation, asking him for ammunition will get you 50 5.56mm rounds, 60 10mm rounds (replenish your ammunition to max before asking, you'll get the rounds and have more than the "max") and 10 more microfusion cells. He serves as your companion from this point on.

Destroy all 3 artillery guns
As you leave the cavern, you will notice a small bunker on the cliff on the other side of the ravine, the only way to it is across the large pipe, inside you will find a health dispenser, and a door to field storage area. Pick the lock (very easy) and enter the room. Inside you will find a computer terminal, the first of ten pieces of intel (1/10) underneath the desk and a holotape titled 'Bombardment'. Leave the building and carry on up the path and across a bridge and you will be facing the locked door to field storage (very easy), in this room you will find another intel suitcase (2/10) at the back and a holotape titled 'Goodbye'. Afterward, head towards the Chinese artillery outpost, which has two bunkers and one big Chinese flag. Two Chinese soldiers will fire on you from above, and two Mark III turrets open up from the left. Approaching the left bunker will spawn a Chinese inferno unit, a trooper with a flamer, and nearly double the health of the regular Chinese soldiers. Alternatively, if the player looks to the right just before the opening that leads to the suspension bridge to the Artillery Outpost, there is a red door leading into the cave passage. On the other side of the door is a single Chinese soldier, and a staircase that winds up the side of the cave. This staircase leads to another red door that deposits the player on a cliff landing on the right side of the artillery outpost, above the bunker with the turret and in line of sight of the bunker above the door to the artillery outpost. From this vantage point, the turret cannot sight the player and the Chinese soldiers are much more easily dispatched.

Entering the outpost will leave you in the sights of several more soldiers. Climb the stairs in front of you and follow the path until you reach a very easy locked door on your left. Inside is another intel suitcase (3/10), another holotape titled 'Invasion' and a Stealth Boy. Take a right, and follow the linear path, dispatching enemies along the way. You'll reach a hallway where the right side drops away, and you'll have a distant view of the Chinese Chimera tanks. To the left just past this area is a locked terminal (very easy). Inside are a pair of grenades, a terminal with more back story details and the last intel case for this level (4/10). Along the way you will begin to come across stacked shells and will eventually find a room with two staircases and several Chinese soldiers. There is a Health dispenser in a small room beneath the right staircase. After ascending either staircase and passing through the door to the west, before continuing left be sure to look right for a very easy locked door, behind the door is a holotape titled 'Overrun'.

More foes will bar your progress, until you reach an open room with several stairwells and many stacked shells. At first glance, the room is empty (Benji will even say something to that effect.) but within moments, you'll be attacked by three Crimson Dragoons, China's advanced stealth units, wielding Chinese officer's swords.

Outside again, you are at the artillery overlook, right next to where the guns are firing. Reaching the guns is no easy task, as each is guarded by a platoon of regular troops, inferno units, and Chinese snipers, Crimson Dragoons armed with sniper rifles. Before you can enjoy the explosion, you have 20 seconds to get a fair distance away from the rigged gun. Repeat the process on the other two.

Once all of them are destroyed, you are told to report to General Chase in the U.S. Army Field Headquarters. You will teleport there, thus beginning the quest Paving the Way.

Report to General Chase
You are teleported away from the mountain top and find yourself right in front of the general. This automatically concludes the Guns of Anchorage.

Behind the scenes

 * Markings on the shells give their size as 914 mm, the same beas those fired by the giant Little David heavy mortar in real-life. Their shapes are also about the same.
 * The title is a take of the WWII film, The Guns of Navarone.
