  Internal information in chain of command linked to that area should have that information.
  And, will do was is necessary to not communicate it in real time nor fully after delay.
  Enemy could identify how information travel and how they react to it.
  As simple civilians, we should just "wait and see".
context: What's that twitter user's source though? >
  
  Most of it is found on telegram channels run by both pro Ukraine users and pro Russian users, including on the ground soldiers who post updates when they shouldnt. Then you have the official sources like ISW, Ukraine and Russian releases. On top of that you have people who have nothing better to do but look at every source available and compile it into easy to digest rough estimates of the battle lines and that's what usually gets posted to Twitter and Reddit. 
  It's never going to be exact and things can change in an hour but it's probably the best you can get. The official sources almost always lag behind so a lot of people just go off recent combat footage and look for landmarks to confirm, and if you've ever seen some of the best players of geoguesser I wouldn't doubt that they are getting it spot on most of the time.
