You All Saw ...

 ... by now Kaja Kallas' X-Rays. I merely remind you. 

But on a more serious note. Here are HQs and Command Post of one of the brigades (36th) of the Russian Army. 

Brigade is a highest tactical level and is before operational-tactical one, which starts with the division. One of the astonishing achievements of SMO was what could only be described a Dynamic Form of Organization Of Troops (Command and Control structure) where suddenly a traditional TOE of the units doesn't matter, since it becomes very fluid and could transform itself in real time depending on combat tasks. In other words classic field/combat manuals change on the fly and, as experience of SMO tells--there could be companies which can grow in strength to a battalion size/firepower, or brigades literally disassemble and reassemble into something else altogether on the fly. Russian military thinkers have been writing about it for years. The latest one from January, 2026 issue of Voennaya Mysl' (Military Thought). 

To the greatest credit to authors, they immediately issue a caveat that Artificial Intelligence (AI) term DOES NOT denote AI, but merely highly developed algorithms and massive processing power. It is happening as I type this.
