ODA Green Anodizing

ODA's (Operational Detachment Alpha) are the boots on the ground operational teams of a Special Forces Group. This color began as a special run for a deployed ODA. In continued support we have decided to continue the color as a standard offering and donate a portion of the proceeds to The Green Beret Foundation. Finish is anodized in green.
