If otherwise allowed to rout (i.e. No other LOS than the ones presented are there), the broken unit may/must rout out of the AFV's Hex/Location A10.51 ...A routing unit may never move ADJACENT to a Known enemy unit, unless in doing so it is leaving that enemy unit's Location. It would rout to the woods hex & would remain there as the AFV is considered Broken (so indicated and strongly intimated by the color of the Shock counter). This would only be different if a UK vehicle is not considered Broken (doubtful, but not certain). In that case the Russian broken unit could rout to the woods and then redirect from there as jrv has noted because the UK AFV cannot interdict.
