Military action against Czechoslovak Legion was one of if not the biggest military actions Soviets did. Not against Germany, Austria, Turkey, UK, Japanese, national republics or White Army.
It was the backbone to the White Army revolt in itself, which was virtually impotent without it.
Or do you think anyone cares about few thousands meme troops from Entente occupying Murmansk & less than half of Odesa, denying Finns and Ukrainians those ports, until Bolsheviks came and asked them to leave? I think
@Jopa79 can tell how Entente was hostile more to Finland than to Bolsheviks for the most part, especially at first.
