Got a job for you, Marked One...
The player can visit this location before obtaining the documents in the Agroprom Research Institute but the Officer will refuse entry.
After retrieving the documents and reaching close proximity, the Warrant Officer will broadcast a message, stating mutants are about to attack the checkpoint. He also says anyone who helps will be rewarded.
Once the attack is over and the door is open, the checkpoint no longer serves as an important landmark in the Marked One's quest. Occasionally though, bandits, mercenaries, Spetsnaz, and a few mutants will assault the checkpoint.
There are two storage containers in the checkpoint.
In Clear Sky, Freedom instead maintains the area. The only other difference is the doors to the Rostok Factory/Army Warehouses are sealed until later in the game. If Duty is favored, they may take over the checkpoint.
