A body armor accessory adds protection to unguarded areas of conventional body armor. The removable accessory comprises an axillary panel having a coverage area and is made of material that impedes the penetration of a foreign object. The accessory can be worn on either the left or right side of the wearer. The coverage area to the deltoid and flank areas of the wearer provided by the axillary panel is greater than that provided by the vest without the panel. A deltoid panel provides added protection to the deltoid area of the wearer.
