10+ years ago I was working on a project and posted a picture with some homes in the background. Minutes later someone else in the project posted a Google Earth screenshot with the exact fukking house I was in front of marked. He didn't have any information other than that I was in L.A., everything else he got was guessing which part of town from the look of the neighborhood and then matching the shape and color of the roofs in the picture to the right spot on Google Earth. And he did that shyt just for fun. Nowadays if I post a pictures of a sensitive location for any reason, I'll even crop out and blur the fukking horizon if I think the buildings or mountains behind the shot would allow someone to triangulate the location.
There are games people play online where someone posts a picture of a random spot in the world, no famous landmarks, and you try to find the exact location on Earth solely from contexual clues and Google Earth.
If people are accomplishing that sort of shyt just for fun, imagine what a team of people helping out the military could do if they already know which country you're in, already know what part of the country you're in, and have
multiple pictures to work with. And who knows wtf A.I. can add to the search. If I were these guys I wouldn't post a single fukking picture from the front unless it was within an entirely closed space or our forces had already left the region.
