Final answer:
The question is about the shoulder insignia surface and stripe widths of Warrant Officers in the military.
Step-by-step explanation:
The question is referring to the shoulder insignia surface of Warrant Officers in the military. Warrant Officers wear a black cloth shoulder insignia with stripe widths specified for the sleeves of blue coats. While the question mentions blue breaks, it does not provide specific details about the length of the breaks. Therefore, without more information, it is not possible to determine the length of the blue breaks.
