Death to Spies: Moment of Truth/Lightning

Lightning is the first mission in the expansion, where the Russians want to capture an experimental plane. To do so, you will need to prepare the airstrip for the operation to allow your squad to appreoach

There are six objectives. Four of these objectives are shown when you start: Capturing a pilot, Disabling the radar, capturing a mechanic, calling the squad. Two additional objectives are added later, to disable the AA guns and to reach the rally point.

Approaching the base
Just north-east of the insertion point are two German soldiers near a car. You can sneak up on one, knock them out, and change clothes. If you have a russian SMG, you will have to drop it here, and replace it with the MP-40.

Enter the car and drive east. Disembark in the parking lot.

If you failed to get usable clothes, you can still approach the base on-foot. Instead of going to the parking lot, you will instead have to turn left for the alternate entrance that leads to the airstrip.

The soldier uniform allows you to travel through the base, but buildings containing important things are still guarded.

Identify the pilot
Before you can capture the pilot, you will first need to identify them. They can be identified by checking documents in the Officer's H.Q., just north west of the parking lot. However, there's two guards the block the front entrance.

To safely enter the building, jump on the crates, and smash the east window when nobody is looking. Enter from the side. You first need an officer's uniform, located in the right-hand room from smashing the window. Change into the officer's room, and head to the marked location on the first floor. The door to the records is locked - you can follow another officer inside (and kill him as he's the only one who enters this room), or pick the lock when nobody is around.

Once you view the records, the two pilots will appear marked on the map.

Capturing a pilot
There are two pilots in the base.

The easiest one to catch is found in the barracks area, in the south-west corner of the base. He follows a simple route - he inspects the plane, walks to the front of a warehouse to talk with a quartermaster, enters the side of the warehouse, and enters his house for a minute.
 * Barracks pilot

He is most vulnerable as he enters the side door of the warehouse. While wearing an officer's uniform, tailgate the pilot as he enters the warehouse. When the doors close behind you, knock out the pilot, and move him into a corner out of view. If you alerted some of the soldiers by the noise, wait for one to enter, and take them out while keeping noise to a minimum.

The other pilot will wait in front of the command center, and will want his plane to be fueled. Find a fuel truck on the base, and bring it to him. He'll instruct you to refuel his plane #24, and will follow you there.
 * Command center pilot

This will put him in a position where he's not easily found by others, allowing you to stun him and move the body to where it won't be passed by patrols.

Disabling AA guns
There are two anti-aircraft guns that need to be destroyed. They're trivially destroyed by applying hydrochloric acid or dynamite, but they're heavily guarded.

First, find civilian clothing. There is one in the warehouses south of the command center, and if you can sneak into the infirmary, you could take the clothing there (as long as you find a way to hide any bodies, as the infirmary will be visited later.)
 * South-west AA

When you're in civilian clothing, enter the infirmary and take the laxative when nobody is looking. Head to the south-west corner of the base, and add the laxative to the stew. After a few minutes, the AA crew will eat some of the stew, then run to the infirmary - this allows you to safely apply the acid without getting caught.

Disabling the radar, capturing a mechanic, calling the squad. Two additional objectives are added later, to disable the AA guns and to reach the rally point.

One of the buildings in the barracks has a uniform for a member of the AA crew. The door to the building is locked, but proper timing and quick picking should allow you get inside.
 * North-east AA

When you wear the uniform, you will get called on the radio to go to the ammo hanger. This is located near the north-east section of the base, in the right-hand hanger. Enter a nearby empty truck, and drive it to the back of the hanger. The solider outside will ask you to follow him inside, and tell you to confirm the location of the shells. This means you'll need to take the "blanks" plate, and swap it with the "live ammo" plate, but you can only swap the plates when you aren't observed by others.

After swapping the plates, order the truck loaded. The others will carry the blank AA shells to the truck, which you can transport to the north-east AA. Park the truck on the left of the tank traps, and disembark - the troops will load the AA guns later, and thus ensure the gun will not function.

Alternatively, you can exploit the AI by approaching the anti-air battery to have them tell you to leave. Move back, and they'll return with their backs towards you, allowing you to quickly kill them.

Capturing a mechanic
Capturing a mechanic is a secondary objective, but it's easily completed. Enter the left most hanger, and stun the mechanic that's working on the front of the plane. Hide the body, and leave when you're certain the other mechanics won't discover it - you can shoot the other mechanics if desired, as there are no additional patrols in the hanger.

Disabling the radar
With an officer's uniform, approach the radar tower in the north-west, when the patrolling guards aren't looking. There are two people inside, which need to be neutralized.

You can distract one of the people manning the station by cutting off the fuel supply.

Inside the radar station, move up to the console, and break it. Once you do so, you will have 50 minutes to call the squad.

Calling the squad
There are three locations to call the squad. The easiest is to use the control tower in the middle while wearing an officer's uniform, and operate the radio when nobody is looking.

The second radio is located in the command center in the upper floor. However, it is protected by a single officer who will announce that he's the only one authorized to use that radio. Using this radio will require you to approach it when nobody is looking, or otherwise neutralizing those in the room.

If you have trouble reaching either of those radios, you can still return to the starting location, and have your assistant call the squad on his radio.

After calling the squad, you will have 30 minutes to reach the rally point, which is on the south of the airstrip.
