Womp womp.
Turns out NATO/The West doesn't have an unlimited supply of armoured vehicles, and the NAFO-donated Nissans all got destroyed. Maybe Denmark and Netherlands can send over bicycles and Ukraine can build itself a WWI-style cycle brigade.
This would be funny if it were a movie, but since it's real life it's tragic and it makes me sad+mad that Zelenskyy and his NATO handlers won't just surrender.

Apologies for the source (I know some dislike MoA), if there was similar analysis from another source I'd post that.
In addition to the 153rd becoming an infantry brigade, the article claims, it seems the 152nd is also slated to become an infantry brigade.
It's been a while since Western countries have bragged about a large shipment of tanks and IFVs/APCs to Ukraine, and they've been focusing on missiles, F-16s and artillery shells. The West is simply out of armoured vehicles to send, and since Ukraine can't make their own, it makes sense that brigades will be de-mechanised as Russia keeps destroying Ukrainian vehicles.
And the 32nd rocket artillery became regular artillery.
