"every single Soviet game" = 13 out of 28 (slightly less than half)
"most of the time results in a win" = 9 out of 13 (more than half, but the map pool would be interesting to see as some maps in tournament pool do favor allies)
It is completely broken in comparison to Guard Motor and Shock Rifle, which won something like 1 out of 6 matches.
not to mention that most of these soviet wins were against MUCH lower skilled players (see vonivan games).
It would be like saying USF is op because devm completely steamrolled fahu...
