This seems like a job that would be labor intensive, involving difficult to source equipment, and have to occur in China or Russia. This seems strangely difficult for what would ultimately kill one soldier at a time and would be discovered one way or another very quickly. Ukraine has shown it can operate in Russia. Even so this seems strangely difficult to pull off from the Ukraine for what would be a low value target that could be replaced relatively easily.
