Neither of the forces fighting in Ukraine are capable of conducting deep shaping in the division/corps battle space.From Foreign Policy, one possibility of a NATO - Russia conflict:
A Russia-NATO War Would Look Nothing Like Ukraine
Moscow will seek to avoid a full-on war and focus on breaking the bloc’s resolve.foreignpolicy.com
That said, a whole lot of our NATO partners cannot be adjacent supporting units to add to combat power due to the speed of staff they can achieve. The Brit’s or French can live in the ATO cycle and their ground brigades can keep up, but the Poles, Greeks, or Italians would be well and truly F’d. And unfortunately due to NATO not wanting to call out the lack of capabilities across its formations and staffs or provide a central priorities of effort to each participating partner it’s gonna be crap show if it ever has to work together.
The whole 5:1 advantage in the offense isnt just a numbers game, it’s an ability to wield a guidon that is echelons above what your opponent and coordinate and wield. NATO can’t do that as a whole. Oh, and to conduct the offense you have to have the ammunition and resources to consume which NATO has a real problem with.
