Steal a box from the security checkpoint

Sidorovich tasks Marked One with stealing the case with unknown contents from the military checkpoint at Cordon, which is being guarded like it contains "pure plutonium".
== Walkthrough ==
=== Location of the case ===
The case location is randomized, but it always spawn on the eastern side of the road, either in the barracks or the commander watchtower.
=== Option 1: Head-on attack ===
If you haven't wiped the Cordon checkpoint out yet, refer to Cordon#Military checkpoint for details on the first attack. Doing that after shutting the X-16 brain down will allow you to collect the expensive exosuits as loot.
If you wiped the checkpoint out before, it will be guarded by the usual small squad of ~10 soldiers.
=== Option 2: Sneaky route ===
If you want to sneak inside, you might also want to at least trigger the attack on the Rookie Village by killing one of the soldiers patrolling the main road before sneaking in. Otherwise the helicopters will fly in and attack you while you're pinned down in the base, making your life significantly harder.
Sneaky route is the same as in Shadow of Chernobyl - follow the eastern fence, cross the fallen tree, jump to the cabin, the outhouse, and the attic of the barracks. Doing this at night is easier as there's less guards. However if the case spawns inside the tower it might pose a problem for you, as the tower always has someone watching it, even at night.
=== Stealing the case ===
After picking the case up, a group of 15 soldiers will spawn around the checkpoint and start closing in. After several seconds, a group of 18 friendly stalkers will also spawn and begin fighting them. Three of these are the invulnerable Kuzka's Mother, Glimmer Man, and Buusty.
The soldiers will continue spawning in waves until they reach 32 in total. The heavy fighting will almost inevitably leave only those 3 invulnerable stalkers alive, all of whom have dialogue for you. Buusty in particular has a lucrative long-term task for you in return for their help.
=== Delivering the case ===
Bring the case to Sidorovich to receive your reward and instructions to deliver the case to Barkeep.
== Notes ==
* It's probably in your interest to sit inside after picking the case up, letting stalkers die. They drop good loot including machineguns, and will steal everything from military bodies if left alive. Before picking the case up, drop a rucksack somewhere nearby and gather all the loot there.
