Yep. The tsar even felt compelled to head towards the front to lead in person. To varying degrees of failure.
Shortly after all this, the British, Americans, Japanese, and other assorted allies invaded Russia, largely, on behalf of the Russian White Army (and to attempt to extricate the Czech legion). That would be the time frame I would expect there to have been conditions that meet the initial post's parameters. Communist pilot vs. Americans in planes capable of landing in open fields. But I haven't found any indication that the US had any (substantial) Air Force present.
