The Cavaliers Drum and Bugle Corps (also known as "The Green Machine") is a World Class competitive junior drum and bugle corps based in Rosemont, Illinois. The Cavaliers were one of the thirteen founding member corps of Drum Corps International and is a seven-time DCI World Champion. The Cavaliers are the only active all-male corps in the activity. History The early days The Cavaliers Drum and Bugle Corps was started in 1948 by Don Warren, Scoutmaster of Boy Scout Troop 111 in Chicago's Logan Square neighborhood after being impressed by the Racine Scouts.

At the Spectacle of Music in South Milwaukee, the Cavaliers were winners in Class B, while all the corps considered to be "big corps" were in Class A. They capped the season by finishing in seventh place at their first American Legion Junior National Championship in New York City. In 1956, the Cavaliers had risen to the number one ranking in the Midwest, but could only manage a third place finish at VFW Nationals. However, in 1957, after trading victories with the Madison Scouts and the Belleville Black Knights, the Cavaliers won not only both the Illinois State American Legion and VFW titles, but also their first VFW National title in Miami. Their win broke the stranglehold that the East Coast corps had held on the national championships. Although the win was considered by the East Coast
