Bond Volunteers are second classmen who compete to become Summerall Guards for the following year. Each spring they are trained in marching and in the rifle manual by the current year's Summerall Guards. Physical training is emphasized. Those who make it through all the training process are designated as Bond Volunteers. The term "sixty-one minute man" refers to those Bond Volunteers who can hold up their rifles for 61 minutes. The top 61 of those Bond Volunteers who achieve the lowest "cuts" are chosen to be next year's Summerall Guards. On Corps Day of their junior year, those who have made the cut are designated as Summerall Guards and will exchange rifles with this year's senior Summerall Guards. (Sources: Dennis D.
