In the U.S. Army, inverted chevron sleeve marks indicate a soldier's rank and length of service. Specifically, they are worn by non-commissioned officers (NCOs) and represent the ranks of sergeant (E-5) and above. Each inverted chevron signifies a higher rank, with additional chevrons denoting years of service in that rank. This system helps to quickly identify a soldier's rank and experience level.
4 years equals one chevron stripe worn at the bottom of the sleeve near the wrist.
Service alpha chevron placements for Marines typically involve positioning the chevrons on the sleeves of the uniform. For enlisted Marines, chevrons are worn on the sleeves of the dress blue coat and the service uniform, with specific placements depending on the rank. Generally, chevrons are located on the upper left sleeve, with the point of the chevron facing upward. The exact placement can vary slightly based on the uniform type, so it's important to refer to the official Marine Corps Uniform Regulations for precise instructions.
The chevron is to be placed 4 inches below the shoulder seam and centered.
The 6-month overseas stripe is worn on the US uniform on the lower LEFT sleeve, just above the cuff. During WW1, this was where the Wound Chevron was worn. So some soldiers who saw service in WW1 and WW2 may wear both on the same sleeve at one point in time.

The uniform of a Sergeant Major in the British Army typically consists of a dark blue or green tunic with distinctive insignia, including rank badges on the sleeve and often a lanyard on the shoulder. They wear trousers that match the tunic, and their uniform may include a peaked cap or beret, depending on the regiment. The Sergeant Major's uniform is completed with polished boots and specific decorations or medals that reflect their service and achievements. Overall, the attire is designed to convey authority and professionalism within the military hierarchy.
