Hello, UN anon!
I know that NATO is required as an international organization to note 'publicly' - newsletter and circular - the major/key movements of its employees. That includes troop movements, although those can be VAGUE - like 'western hemisphere' vague if security is a concern. If a member state doesn't wish for its troops' locations to be mentioned, NATO will bend to those requests. I'm sure you're correct that the UN has its own rules.
The UN is well-meaning, but just needs to rein it in. 'Let's end global poverty!' What? How? It's the equivalent of saying, 'Let's turn copper into gold, or air into gold!' Small steps, UN, small steps.
