A gold color metal shell and flame 1 inch in height.

The use of the ''shell and flame'' by the Ordnance Corps dates back to 1832; it is considered to be the oldest branch insignia of the Army. Similar insignia had been used by the British Army. After its adoption by the American Army, the design was used by the Artillery as well as the Ordnance until 1834 when the crossed cannon was adopted by the Artillery. In 1835, the shell and flame was used on a button for members of the Ordnance Corps and the design had been used in various items worn on the uniform since it was first adopted. The simplicity of the shell and flame harmonizes with the armament of days gone by, while the action it connotes is applicable with equal force to the weapons of today.

The plaque design has the branch insignia, letters, and rim in gold. The background is crimson.

A gold color metal and enamel device 1 1/8 inches in height overall consisting of two gray antique cannons in saltire on a white disc behind an encircling scroll in the form of a buckle red belt with, between the intersecting cannons and the belt, a black antique bomb, its scarlet flames issuing at the top of the device from behind the belt, which bears the inscription "ORDNANCE CORPS U.S.A." in gold letters. The regimental insignia for the Ordnance Corps was approved on 25 March 1986.

There is no coat of arms approved for Ordnance Corps Regiment. The regimental insignia (all in yellow except the letters on the insignia are crimson) is displayed above a yellow scroll inscribed "ARMAMENT FOR PEACE" in crimson. The background of the flag is crimson and the fringe is yellow.

The crossed cannons are representative of the Ordnance Corps' early relationship to the Artillery. The flaming bomb, also known as the shell and flame, represents the armament of days gone by, while the energy it connotes is applicable to the weapons of our own day. The cannoneer's belt, which encircles the flaming bomb and crossed cannons, is embossed with the words "ORDNANCE CORPS U.S.A." and represents the traditional association between munitions and armament. The white background symbolizes the Ordnance Corps' motto, "ARMAMENT FOR PEACE."
