90th Personnel Services Battalion
The 90th PSB mission is to provide personnel services and postal support in our assigned area of responsibility, transition to war/stability operations, deploy the PSB/subordinate elements, and sustain operations.
The distinctive unit insignia was originally approved for the 90th Replacement Battalion on 27 Apr 1966. It was redesignated for the 90th Personnel and Administration Battalion on 26 Apr 1978. On 24 Jun 1994 the insignia was redesignated for the 90th Personnel Services Battalion, consisting of a blue five-pointed star with one point up and charged with a gold escarbuncle of five rays, each terminating in a gold fleur-de-lis between the points of the star. The five fleurs-de-lis refer to the unit's participation in five campaigns during World War II. The escarbuncle is a symbol derived from the bracing fastened to the back of the medieval fighting man's shield to strengthen and support it and is used in this instance to signify the unit's service in supporting and strengthening American combat units (represented by the blue star) as a Replacement Battalion during World War II and in Vietnam.
