The mark consists of a blue circular ring with a thin black outline, around which a yellow rope creates the outer boundary. A white circle appears between the blue ring and the yellow-rope design. The words "MARINE CORPS INSTALLATIONS COMMAND" appear in white within the blue circular ring and the term WEST separates the terms "MARINE" and "COMMAND" at the bottom of the blue ring. Within the blue circular ring is a white circle containing an emblem comprised of a gold, black and white eagle perched atop a black and white lined globe showing North and South America in gold with a thin black outline. In the eagle's mouth is a streamer. A partially obscured gold and black anchor with a gold and black anchor line appears behind the globe design. Beneath the emblem design is a horizontally-oriented cord of alternating gold and red colors. Beneath the cord is a shield, with three fields of red and one of blue, separated by a gold zigzag lightning bolt pattern. At the center of the shield is a wheel-shaped circular design. The hub of the wheel is gold with a blue ring and has thirteen gold spokes connected to a larger gold rim of the wheel. A red background appears behind the spokes. A larger blue ring containing thirteen gold five-pointed stars encircles the wheel design. The blue ring encircling the wheel design also has a thin gold outline. Behind the shield are two crossed sabers. The saber with the hilt on the left is grey, gold and yellow with a thin black outline, while the saber with the hilt on the right is grey, gold, yellow and black with the saber blade having a thin black outline. A banner of red and gold containing the gold wording "MCIWEST" appears beneath the shield design and is partially draped over the lower portions of the crossed sabers.
