Shield
Brick red and yellow are the colors of the Transportation Corps. The gyrons are representative of the unity of purpose of the organization, while the pheons are symbolic of the dexterity and nimbleness of wit of personnel of the organization in the performance of their duties. The pheons, the eight gyrons, and the four quarters of the shield as set off by the arrangement of the colors of the gyrons are suggestive of the numerical designation of the organization.
Crest
The crest is that of the U.S. Army Reserve.
