We adapted to Small Unit Tactics decades ago, with a huge emphasis on empowering a strong SNCO core, and junior officers who could make tactical decisions on the fly. We are all given the commander's intent, and understand the basic mission objective we're going on. Absent of that we know the intent, so if we lose our leadership we can easily pick up where they left off and complete the mission.
Russia is not doing this, which is why so many Generals, Majors, and Colonels, are getting killed. They're micromanagers relying on untrained conscripts. So when things break down they have to get the senior leadership to go down to the front to make sense of it and unfuck it. This puts a big target on their back and gets them killed in large numbers. This is also backed up by the fact that the actual troops on the ground have no clue what is going on. They don't know the tactical OR strategic mission, the leadership is keeping that close to the vest which causes these units to fall apart when their leadership is taken out, or when they reach the current objective they were told about, they stop and sit tight and wait for further orders.
There is a really good Forbes quote about this from a French soldier:
"Anyone with a passing knowledge of Kipling knows the lines from Chant Pagan: 'If your officer's dead and the sergeants look white/remember it's ruin to run from a fight./ So take open order, lie down, sit tight/ And wait for supports like a soldier./ This, in fact, is the basic philosophy of both British and Continental soldiers. 'In the absence of orders, take a defensive position.' Indeed, virtually every army in the world. The American soldier and Marine, however, are imbued from early in their training with the ethos: In the Absence of Orders: Attack! Where other forces, for good or ill, will wait for precise orders and plans to respond to an attack or any other 'incident', the American force will simply go, counting on firepower and SOP to carry the day.
This is one of the great strengths of the American force in combat and it is something that even our closest allies, such as the Brits and Aussies (that latter being closer by the way) find repeatedly surprising. No wonder it surprises the hell out of our enemies..."
