Across 59 TvT ladder games from 7 players with 12 starting workers, 2-1-1 Marine Tank wins 52.5% of decided games. The likely range for its true win rate is 40.0–64.7%, so it is too close to call against a coin flip. It appears in 6.9% of the 850 TvT games in the guide sample. This guide is newly published, so there is no weekly trend yet. This is still a small sample (n = 59), so treat it as a directional read.
