Many people will ask, when sailors can swim, their swimming skills will definitely be high. Actually, it's not like this. You don't have to be able to swim to be a navy.
The navy can swim, in fact, for self-protection and viability. If it accidentally falls into the sea, it is much better to swim than not to swim. In addition, the naval forces have special swimming training. Learning to swim depends on talent. Not everyone can learn to swim. Therefore, the navy does not have to swim, and there is no hard and fast indicator that the navy must swim.
People who want to be navy can try to sign up, but few people will be hired. Try their luck. It doesn't matter if they don't choose. Other arms are also very good. They can defend the country and contribute to national construction.
