High Intensity warfare is the new wording for a major forces conflicts falling back from Asymetric Warfare to World War like battles.
There is a chance that the official statements of Western military are false, but that would mean that they have changed strategy from the Cold War.
The invasion by a main battle group against Charkiw might be a first test of Russia, if they are capable to coordinate main forces instead of being in a hord attack like war stretched out over thousend kilomters in pretty much a half circle. A circle, just for the record, has the largest edge relative to the surface, therefore this war is the largest possible frontline fighting over the smallest possible territory.
There are some things that NATO certainly hasn't got, because they would have talked about it, but the Russians and Chinese might have, and that is large war fare simulators deriving from the gaming industry.
There are several quite realistic strategy games out to order parts of brigades over a battleground like a valley with several villages that display detailed modern military like light infantry, light armoured cavallery, heavy tank platoons and even all kinds of artillery in real time.
There are also very realistic ego shooter varieties that realistically enable to have infantry solders practice tactics and strategies quite realistically.
If both are connected it would create a platform to realistically simulate possibly thousands of potential war scenarios on different areas of this world.
No war comentator with range ever mentioned that Putin created The Russian Missile or Rockets Arsenal as an independent wing next to Army, Navy and Airforce while NATO has Space Force now and there is no information about even wich OS Russians use at home.
This is a known unknown: The Russian War Simulating capabilities.
