Final answer:
The warrant officer rank described is most likely that of a Chief Warrant Officer 2 in the United States Navy, identified by a specific insignia on the sleeve.
Step-by-step explanation:
The warrant officer rank identified by one 1/2 inch stripe with a 1/8 inch blue stripe broken by one hash mark, centered on the sleeve, corresponds to a specific branch of the military's insignia for rank identification. However, without specifying which country or branch of the military service this refers to, it is challenging to concretely identify the exact rank. In the United States Navy, this description most closely resembles the insignia for a Chief Warrant Officer 2 (CWO2) but variations in insignia can occur between different branches and nations.
