A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height consisting of a scarlet pheon, point down, supported on each side by a white quill point down, and centered between the two quills on a field of dark blue, three five-pointed gold stars arranged two above one; attached below a gold scroll inscribed "WE MAKE IT HAPPEN" in dark blue letters.
The colors dark blue, scarlet and white are indicative of the Battalion's association with the Adjutant General's Corps. The two quills represent personnel and administration and reflect their support of the other Army units, represented by a pheon. The three stars commemorate the unit's World War II campaign participation. The motto, "We Make It Happen," is indicative of the role the Battalion plays in the servicemember's career.
The distinctive unit insignia was originally approved for the 326th Personnel and Administration Battalion on 10 January 1985. It was redesignated for the 326th Replacement Battalion, with description and symbolism revised, on 23 November 1990.
