Dark blue and scarlet are colors traditionally associated with the Adjutant General's Corps. The chevron and ermine spots, suggested by the Arms of the City of Lichfield, England, refer to the unit's place of activation and the number of ermine spots allude to that time, during World War II. The chevron is indicative of leadership and determination and symbolizes the overall mission of the unit. The turnstile, a systematic gate, refers to all supervised and controlled processes involving the unit's capabilities.
The distinctive unit insignia was originally approved for the 324th Replacement Battalion on 11 June 1971. It was redesignated for the 324th Personnel and Administration Battalion on 20 April 1972. The insignia was redesignated for the 324th Replacement Battalion, with description and symbolism revised, on 27 April 1992.
