OSINT photo analysis.

According to Greg Scarlatoiu and Joseph Bermudez Jr., the authors of HRNK's report, the the antiaircraft guns in the picture appear to be six ZPU-4s, Soviet-made heavy weaponry first used during the Korean war. They are positioned about 100 feet from the standing figures. A few feet behind the antiaircraft guns, there appear to be a line of troops and/or equipment, the report notes, with buses and trucks at the site suggesting that people had been bused in to watch whatever was happening.
Shout-out for Joe Bermudez. Good job.
