Don't forget Aircraft.
Here's a picture of the AN-124:
Ukraine has a considerable arms industry. Kharkiv at one time (not that long ago) had the largest tank factory on earth. Ukraine made artillery, artillery ammo, atgms, ballistic missiles, APCs, you name it.
I doubt they have a problem doing basic maintenance for a few hundred western artillery systems. Or trucking it back to Poland as needed.

Ukraine HAD a considerable arms industry. Most those factories are now a pile of rubble. Vlad has done well de- industrializing the Ukies, as well de- energizing them. It will take years to rebuild the destroyed factories.
Ukraine is now a welfare queen nation, their billions of debt is unpayable, currency, economy, manufacturing, exports destroyed, infrastructure crippled….
Zelensky’s leadership has destroyed Ukraine.
