ShieldThe shield is white, the color of Infantry facings when the Regiment was organized. The red fess with arrow commemorates the battle of Tippecanoe; the battle of Lundy's Lane is shown by the seven cannons captured there; while the border of green, white, and red is for the Mexican War.
CrestThe crest is a modification of the crest of General Nelson A. Miles who was for many years Colonel of the Regiment and who led it in several notable Indian engagements. His crest is an arm in armor grasping an anchor; 9 arrows, one for each Indian campaign, is substituted for the anchor in the regimental crest.
