In 1969, the band hired a successor to Dvorak, Mike Leckrone. Leckrone expanded the marching band's membership and popularity during the Vietnam War era, a time when the band's connotative association with the military had become unpopular among some students. Women were first eligible to join the marching band in 1974, enabling a major expansion of membership. Leckrone introduced a physically demanding style of marching called “stop at the top,” which required much more athleticism and physical conditioning. He required every member to attend Registration Week fundamental drills to learn the new marching step, updated the pre-game "run-on" Dvorak had introduced, filmed every performance, and scheduled viewing sessions in which he provided feedback. Leckrone's band played a repertoire of Badger songs and tunes, creatively arranging and weaving them into field-show programming.
