It's pretty easy to find Al-Udeid Air Base, which was secret until the mid 2000s. Some of the other details like patrols, convoy routes, and missile battery locations may not be classified, but are probably things the US military would rather not see online
Given the visibility of HN threads I expect this data to get scrubbed post-haste - so download it / archive it ASAP
All I see are people looking at places they already know about and seeing that people have used Strava there. If these people already know the locations, so does anyone else who matters.
Not secret in the sense that the enemies of respective nations already knew them, but secret in the sense that only the militaries knew them, now the whole world does.
I think the patrol routes are more important(fun) than locations.
