The insanity of people in OSINT to think they know more from just publicly released video footages than the Russia military which have intel assets like drones, satellite, signal intellgience and other means...
Its okay to think you are an expert, but to pretend you gonna be better than entire teams of hundreds, if not thousands of FULLTIME SOLDIERS / MILITARY SPECIALISTS / MILITARY ANALYST that does intel collection and analysis work 24/7 (working in shifts by the way) is pure delusional.
Speaking from experience working as one of those full time shift intel specialist more than a decade ago - you have no idea how much a military collects, analyses and know. In details you would never imagine.
Goodness.
Obviously, we have been tracking Ukrainian advances north of Lyman the entire time. We have tons of backdated geolocations, along with video footage, of the attacks dating back a long time. But the operation was deemed sensitive enough to be protected, similar to what happened in Kupyansk and then in south Donetsk.
However, the operation in Lyman seemed even more protected since even the most in the know and honest Russian reporters seem to be missing it. Or at least silent about it. It was honestly shocking to watch how out of the loop the Russians really were, which I think is in large part due to the collective action of OSINT to avoid speaking about the situation.
