The mark consists of Large semi circle open from the 2 o clock to 4 o clock position with two similarly spaced hash marks starting from the inside of the semi-circle and ascending outward through the two and four o clock opening. The semi-circle is tapered in size with radius at both ends. The taper begins at the two o clock position and increases in size around the radius until the four o clock position. The two ascending hash marks have radius ends and are tapered. the smallest portion of the tapered hash mark starts within the semi-circle slightly left of the center of the arc and increases in size as it ascends the opening. The hash marks are equal length and end slightly outside the arc of the semi-circle forming the shape of the letter G. The hash marks do not contact any portion of the semi-circle. The semi-circle is the color blue. The top ascending hash mark is colored green and the bottom ascending hash mark is the same color blue as the semi-circle.
