Where Ukrainian river monitors could be useful

Would river monitors be useful in the war in Ukraine?

They would be most useful in the south, where they could move along rivers and coasts and support crossings.

River monitors offered limited value in the northern campaign but more promise along southern rivers and coasts. Fast shallow-draft craft could shift between waterways, appear unexpectedly, and support crossings. Their mobility would create another direction of manoeuvre against Russian forces rather than replacing land-based firepower. Geography therefore determines whether the same vessel is useful or irrelevant.
