Not just on TikTok, I saw it on YouTube clips from outside the USA. I've know people who've worked on such bases and have heard how strict they were with orders to stop and look away or at the ground when an alarm went off. Well I was pretty surprised to see it and like others, the thought crossed my mind that it wasn't an accident. Furthermore, it looked familiar...I think I saw another diagram picture about a year ago, possibly on a military-tech YouTube channel, possibly by an eastern-european creator. There was discussion at the same time that the next generation was not just approved but already created.
