There are four standstill divisions- Silver 1, Red 1, Silver 2, and Red 2. As far as the 1 and 2 go, it is just that- 1 is for more advanced drumlines, and 2 is for less experienced drumlines. The Silver 1 and Red 1 (more advanced) drumlines compete in the stadium, and the Silver 2 and Red 2 groups compete indoor. Directors can choose whether to compete in 1 or 2. Silver and red, however, are not at the disgression of the director. Red classification is for drumlines with less than 20 members, and silver is for drumlines with twenty or more members. For example, John Horn competed in Red 1 for the last several years, but is now larger, and is competing in silver 1 this year.
