Imperial Japanese Navy OF-1c Sleeve Insignia T-Shirt Design
This design showcases the sleeve insignia worn by officers holding the rank of Shōi-ho (少尉補), or Acting Ensign/Sub-Lieutenant, in the Imperial Japanese Navy during 1942. This rank corresponds to the NATO code OF-1c and represents the most junior commissioned officer within the IJN.
Artwork Details
The central element of the design is a single, very narrow stripe. This stripe, precisely replicated from historical examples, is the defining visual characteristic of the Shōi-ho rank's sleeve insignia. In some instances, a star may be absent, accurately reflecting the variations present in authentic examples. The design prioritizes historical accuracy.
Symbolism and Meaning
The single stripe visually represents a newly commissioned officer, often in a probationary or training status. It signifies the initial step on the officer career path, marking entry into the commissioned ranks. This modest, yet significant, mark of rank conveyed limited command authority, reflecting the role of these junior officers who typically assisted more senior personnel.
