Opposing dancers can also face off in a line formation called the "Apache Line". In contrast to the circle formation in breakdancing, the Apache line allows multiple opposing dancers or crews to face each other and execute their burns. Back in the 1970s it was a fascinating display to watch. Each Rocker must keep in his/her line formation while battling. One form of Apache line competition utilized rotation positioning. In other words, dancers would battle until either he is tapped to step out by another Rocker, or the opponent has been worn down.
