Can't soldiers travel abroad? I'm a senior three, and I'm going to graduate soon. I have the will to apply for the military academy and certain conditions, but I heard that officers and men can't go out. Soldiers can leave the country, but the exit procedures are somewhat difficult. Moreover, if you work in some sensitive departments or troops, there is basically no chance to go abroad, and your family may be restricted. It is even more troublesome for senior officers to go abroad, not only to apply to the army and the party, but also to take notes from foreign institutions in other countries, except for official travel.
