While the album shares the distinct iconography of an eastern European city abandoned in the mid-80s, there aren't any other particular landmarks recognizable from Warzone. U/Lukegiant posted an entire album of photos from his trip to Chernobyl. Redditor u/kuroinnomanga made a compelling case for the what they believe happened in Verdansk, for the game detective types. There are also a number of disaster relief tents scattered around the map, indicating that humanitarian efforts were being made in Verdansk before it was eventually evacuated. There have obviously been some disasters in the area, such as the crashed airplane at the airport. The fictional city of Verdansk was similarly evacuated, though it isn't exactly clear how or why.
I have more pics of the area if anyone is interested. Even the outside of the building is the same. Today I found the exact same pool in Warzone. I visited Chernobyl a few weeks ago and found the empty dive pool.
