Soldiers are the lowest ranks, including first class, second class, third class (recruits) and handyman. The daily clothes of soldiers are marine corps uniforms, including navy caps, white sleeveless vests, blue or green scarves, blue trousers, leggings and brown military shoes. Of course, many times soldiers can choose not to wear hats (please refer to Kirby and Helmeppo in the handyman stage) or just wear hats (please refer to Fullbody and Jango in the third stage).
Non-commissioned officers are above soldiers, including Cao Chang (staff sergeant), non-commissioned officers (sergeants) and corporal. The sergeant's clothes are a little more gorgeous than the soldiers'. He can continue to wear sailor's clothes, or he can choose some clothes of his own, but he must have the navy logo (please refer to Cao Changjian's Big Four Flags and Helmeppo in the sergeant stage).
Officers above the second lieutenant are called "naval lieutenants" (naval lieutenants). At this time, he can put on a coat with the word "justice". Lieutenant usually wears a sailor suit, but there are exceptions to wearing a suit (please refer to Fullbody in the captain stage)
Above major, you have a bigger choice. Generally, you wear a coat outside and a suit of your choice inside, ranging from major to general, but there are exceptions (please refer to Brigadier General Smoker and Colonel T-bone, who don't wear a coat of justice, the smoker wears a leather jacket with justice written on it, and T-bone wears a cloak and armor with navy logo).
Marshal of the Warring States period and hero Karp are both white suits and coats of justice. Of course, behind the marshal's coat is the navy logo.
Of course, I'm talking about a case, and I can't deny it. The navy associated with straw hats also has its own personality in military uniforms. Of course, for the general navy, sleeveless sailor suit+blue pants with justice coat or white assembled justice coat is the most orthodox and classic collocation.
I hope it will be helpful to the landlord and adopted.
