Seriously, if the firehose of American aid gets turned back on, the Russians are in deep fucking trouble.
The ukies are back to where they were before the US aid started rolling in heavy, trading Russian blood for a few sqkm of territory here and there while trying to preserve man and materials as much as possible. But the lack of counter battery action has let the Russians get back to their playbook of stacking artillery and focus firing small patches, then meat waving with infantry.
In the interim though, the Ukies are developing more and better weapons that allow them to strike into Russian territory in absence of the ability to use western missiles to do that.
