At this point with the US foot dragging sending everything the Ukraine needs, the CBUs will help a bit. Until the Ukraine gets more armor, more CE clearing equipment, F16s, etc. the war will drag on.
The Ukraine Military has out soldiered the Russians in almost all situations. They are superior to the Russian mob that they call a military.
The US is learning some lessons from the Ukraine's experience, etc. The Ukraine's maneuver Brigades are more like a TF or BG. A real combined arms team. With an important difference – their Bdes have 4 FA Bns, not one.
Even light units have tank support. And organic transport.
Their Bdes have their own CE Bn, Recon Co., Sniper Co. ADA Bn, etc.
They are much better organized and equipped to engage in modern maneuver combined arms warfare vs. a modern military with tanks, IFVs, FA, etc.
Not the 2d rate Iraqi Armor & Infantry, etc., units. Or the islamic "jihadis"/terrorists/radicals that the West engaged in both Iraq & more so in A'stan. Asymmetric warfare, guerilla insurgent warfare where CD is a more of a concern. And the jihadis, etc. knew that.
The US should not note: 4 FA Bns[including 1 AT], 1 CE Bn, ADA Bn, Recon Co., etc. per Bde.
Light Bns & Bdes should all have Tanks and transport along with the heavier CE, FA, ADA, Recon units, etc. support like the heavier Bdes.
Like after Vietnam the US Military had to rebuild itself to fit the current threat, etc. So, after 20 years in A'stan and based on what we see in Ukraine. The US Army needs to get up to the task of becoming an effective modern mobile combined arms force. That becomes a little heavier with FA, Tanks, CEs, ADA, etc. if we want to be prepped for the "next war" …
That is going to cost money in some case and with our leaderships' current priorities the $ and the will may not be there at this time.
