Final answer:
Service stripes on the Army Blue Service uniform represent three years of honorable service and are placed on the lower part of the left sleeve. They should be sewn with the bottom edge parallel to the bottom of the sleeve, centered between the sleeve seam and the bottom of the chevron.
Step-by-step explanation:
Service stripes on the Army Blue Service uniform in the United States Army are placed on the lower part of the left sleeve. Each stripe represents three years of honorable service in the Army. They are sewn on the uniform with the bottom edge of the stripe parallel to the bottom edge of the sleeve, and centered between the sleeve seam and the bottom of the chevron, if present.
For example, if a soldier has served for nine years, they would have three service stripes. These stripes would be placed in a horizontal row, with the first stripe at the bottom, the second stripe above the first, and the third stripe above the second.
It is important to follow the precise regulations and instructions provided by the Army for properly placing service stripes on the uniform.
