Shield
The chevron, representing the rafters supporting a roof, stands for the Battalion's support function. The embattled upper edge of the chevron indicates capability for combat support; the embattlements are seven in number in reference to the organization's original designation. The white bayonet on the blue background, for Infantry, refers to both the unit's activation in Georgia at Fort Benning, called the "Home of the Infantry," and to its initial assignment to an Infantry Brigade. The white heraldic rose on the scarlet background represents the Cherokee Rose, the Georgia State flower. The gold barbs of the rose simulate a star and refer to the conception of Support Battalions by the Army Staff study entitled "CO-STAR."
Crest
The colors yellow, red and green are those of the Vietnamese Service Streamer and reflect the Valorous Unit Award. The red arrows symbolize combat service; their positions, crossed in saltire, is indicative of strength and support. Rice is a symbol of Vietnam and is the substance of life support in that country. It indicates the support mission of the unit in its most basic form.
The coat of arms was originally approved for the 7th Support Battalion on 15 August 1966. It was redesignated for the 299th Support Battalion on 17 June 1983. The coat of arms was amended to add a crest on 23 January 1984.
