[[File:Marching Band Mallet Percussion.jpg|thumb|An example of a high school front ensemble]]The [[glockenspiel]] is the mallet percussion instrument most often used as a part of the battery. The tradition of marching the glockenspiel as part of the battery is common in many countries, such as in the Filipino [[drum and lyre corps]]. In the early 1970s, mallet percussion was first allowed into drum corps in competitive circuits, such as [[Drum Corps International]]. At first, only [[glockenspiel]]s and [[xylophone]]s were allowed, but starting in 1976 [[marimba]]s and [[vibraphone]]s were also allowed. The [[27th Lancers Drum and Bugle Corps]] even rigged up homemade racks to march [[tubular bells]].<ref name=":0">{{Cite web|title=The History and Development of the Front Ensemble in Drum Corps International|url=https://etd.ohiolink.edu/!etd.send_file?accession=osu1461167753&disposition=inline|access-date=2019-01-13|website=etd.ohiolink.edu}}</ref>

Eventually, in 1981, within North American bands and corps, mallet instruments were allowed to be grounded, as arrangers felt limited by the instruments they were able to write for, and marching the heavy equipment became detrimental to the members' health. Since then, most corps or bands have kept their mallet instruments in the front as part of the [[front ensemble]]. (Other countries, however, have kept the practice of marching the glockenspiel while adopting the front ensemble tradition.)
