Shield
The colors gold (yellow), blue and red are from the wheel of the Quartermaster Corps seal. The shield is divided into two parts to allude to World War II (it was during that eventful time that the historical background of the unit was established). The sun, taken from the national flag of the Republic of the Philippines, and the vair in point simulating waves as in the coat of arms of the city of Manila, indicate the island of Luzon where the organization was awarded the Philippine Presidential Unit Citation during World War II.
Crest
The crest is that of the United States Army Reserve.
The coat of arms was originally approved for the 329th Quartermaster Battalion on 19 November 1963. It was cancelled on 9 January 1969. The insignia was reinstated effective 16 September 1996, for the 329th Quartermaster Battalion. It was redesignated for the 329th Support Battalion effective 17 September 2006.
