Operation: Anchorage! (quest)

Operation: Anchorage! is a quest and achievement/trophy in the Fallout 3 add-on Operation: Anchorage.

Detailed walkthrough
The quest begins automatically after Paving the Way.

After destroying the Chimera fuel tanks and clearing the Listening Post of Chinese presence with their Strike Team, the Lone Wanderer can now push forward in order to disable the pulse field barring American power armored soldiers from attacking the Chinese base of operations.

This time, the player character has to make do without the assistance of their squad. Instead, Sergeant Montgomery alone accompanies the player character. Leaving the American H.Q. take the path dorectly ahead, through the bombardment. Follow the path (the game basically forces the player to follow this path so it really can't be missed) until coming to a trench that is manned by American soldiers. Move through that trench until reaching to the next trench section, this one filled with hostiles. Shortly after entering there will be a wooden shack to the left. Inside is a health dispenser and a captured American soldier. He is sitting in front of a piece of intel (9/10).

Continue fighting through the trenches untill arriving at the final line of Chinese defense, the pulse field. As demonstrated by American power-armored soldiers, soldiers wearing power armor are not able to enter the field safely, which is why it's the player character's job to head to the Pulse Field's control building on the far right and disarm it. Inside this building is the final piece of intel (10/10). Its is on the crates to the left of the Field's deactivation switch.

With the pulse field deactivated, it is time for the assault on the Chinese compound, an occupied refinery. The power-armored soldiers begin their attack on the Chinese compound turrets, and eventually destroy the front gates revealing the door to the final confrontation with General Jingwei. Cross the field and enter the building. Upon entering the refinery the player character will freeze as Chinese soldiers and American soldiers (with Benjamin Montgomery) begin to fight. Among this fighting, the player character will witness General Jingwei, commanding officer of the Chinese troops at Anchorage, executing an American captive with his shocksword.

In the following dialogue, the player character can convince him that the battle is lost through a Speech check, resulting in Jingwei committing suicide with his sword. If the player character does not pass the Speech check, then the general will attack the player character. He has high HP, and is the strongest non-player character in the game. His shock sword also deals a considerable amount of damage.

Once Jingwei is defeated, all non-player characters are frozen in place (except for Montgomery, who can be spoken to one last time) and General Chase, who appears right in the middle of the final battle and tells the player character that the simulation is over. He also rewards the player character with the Covert Ops perk if one has obtained all intel suitcases. The player then leaves the virtual reality and returns to the VSS facility.

Back in the simulation pod at the Outcast outpost, the player can now proceed to the terminal at the opposite end of the floor (where the Outcasts are already waiting) and open the armory. Inside, the player character will find assorted weaponry, ammunition, and other supplies including some unique items; refer to "Reward" below for a detailed listing.

Upon opening the armoury, Defender Sibley and Protector McGraw start a dispute. Sibley does not want to share any of the unlocked equipment with the player character whereas McGraw insists that "a deal is a deal." The disagreement results in a revolt by the defender and most of the unnamed Outcasts against the protector and Specialist Olin, with the player character ending up as a target for the mutineers as well. If the player character protects McGraw from Sibley's attack he will reward the player character with some friendly dialogue. If Olin survives, she offers the player character her ability to repair their equipment, however, her Repair skill is only equal to the regular Brotherhood scribes at 51%. However, if Defender Sibley is killed before entering and completing the simulation then the revolt never happens, but Olin still offers to repair one's equipment acting as though the revolt went and gone, but this is not the case for Protector McGraw who acts as though the revolt never happened.

Reward
Upon completion of Operation: Anchorage, the player character acquires the Power Armor Training perk if they don't have it already. In addition, the player character is granted access to an armory within the Outcast outpost.

This room contains several unique weapons and armors:
 * Winterized T-51b power armor
 * Winterized T-51b power helmet
 * Chinese stealth armor
 * Jingwei's Shocksword
 * Trench knife
 * Gauss Rifle

Along with other more common items, such as:

Intel suitcases
The last 2 of the 10 intel suitcases required for gaining the Covert Ops perk can be found during this mission. Please refer to the main article for their locations.

It's also possible to return to the areas to get the cases from Paving the Way if they were missed.

Bugs

 * At times, after exiting the simulation one's Geiger counter will continue to click. Reverting to a previous save anytime in the simulation will not fix it nor will moving to a different area or quitting to the main menu and reloading. One will need to restart their console to fix it. Leaving the Outpost via the elevator will also fix this bug.
 * On occasion, if the Wanderer convinces Jingwei to commit suicide, he will attempt to stab at himself, but he will miss, and still die. This can make some humorous results.
 * If one enters the Chinese Compound at the same time as one of the power armor soldiers, sometimes the game will be locked in the cinematic mode and will not be able to experience the dialog with Jingwei. Neither Jingwei nor the Wanderer will be able to move and one must wait for one of the soldiers to kill him or quit the game and reload from the main menu. It is also possible to kill him using console commands to fix the issue. If loading from the menu, Jingwei's dialog should commence.
 * Sometimes, if loading an autosave of the Chinese HQ with Jingwei, one will be stuck in cinematic mode and the game will not continue. To fix this issue, load a different save file and reload the autosave, or kill him using console commands if playing on the PC.
 * If one chooses to fight Jingwei, after a fairly short period of time the T 51-b soldiers may turn hostile. The Chinese soldiers turn friendly as well. Whether this is a bug or due to over-sensitivity to friendly fire, or an intentional feature, is unknown. One possible solution to this bug is by going near the Chinese sniper on top of the crates in the back and jumping from a barrel to the top of one of the crates and hiding there until Jingwei is killed.
 * The Covert Ops perk may not appear in the Wanderer's Pip-Boy Perks after collecting all ten Intel suitcases.
 * When in the hallway of the listening post one can somehow complete 'Picking up the Trail' by talking to Montgomery without ever being close to the caves.
