There is only one submarine academy in Asia, namely Qingdao Submarine Academy. Dalian is specialized in training surface ships, and its name is Dalian Naval Academy. Other soldiers only need about 3 months, and submarine recruits need to train for 5 to 8 months. But when the distribution is better, it will be easier to get off the submarine detachment. Food expenses are in the forefront of the whole army. It seems that only divers and pilots are taller than submarine soldiers.
