The Niagara University Crest: Upon the recommendation of LTC John H. McKinnon, PMS&T and with the approval of Francis L. Meade, C.M., and the Army Institute of Heraldry, a regimental crest was designated in November, 1951. The purple and white crest combines elements of the Vincentian heritage with the Niagara University purple eagle, from which the "Purple Eagle Battalion" draws its name.
