Wear military uniform all the year round and play three numbers.

Hello, would you like to ask the place where you wear military uniforms all the year round and play three numbers? Wearing military uniforms, playing three numbers all the year round, from the night of the military port. Every year, you have to wear a military uniform and play with three numbers, which means you have three responsibilities: defending your country, uniting the people and sailing the ocean.
