Coat of Arms T-shirt?

[Friday]

As for heraldry in the US you need to look closely at US Army uniforms. The Army has a heraldry department and each army solider wears at least two heraldry devices. On the left shoulder (closest to the heart) is the Corp or divisional unit insignia. On the Epaulettes is the regimental Distinctive Unit Insignia (DUI). If the person was in a unit in a combat zone for over 6 months(?) they wear the combat divisional unit insignia on their right shoulder. I am not sure under the changing uniform regs how or where these insignia are worn.

The DUI for the 4th Field Artillery contains military heraldry symbols for their service in Mexico, Philippines, and for their stand at Gettysburg at the point of Picket's charge.
