1905 in may, radio communication appeared in the naval battle between Japan, Japan and Russia. Japan's United Fleet uses wireless telegrams to provide information to Japan's United Fleet Command in time. At the same time, the Japanese navy used electronics to interfere with Russian radio communication, which plunged the Russian army into chaos and forced the Russian fleet to lower its flag and surrender. This battle captured Russian warships 19, with more than 1,000 casualties1/KLOC-0. The Japanese only lost three boats, with more than 700 casualties. The Japanese army performed a live drama by means of radio communication.

During World War I, radio stations, wired telephones and telegrams were equipped to the battalion command post. Since then, military communication, as an important part of combat effectiveness, has been active in all fields of the war stage with a brand-new look. As mentioned earlier, in June of 194 1, Hitler launched a large-scale surprise attack on the Soviet Union. Shortly after the start of the war, the wired communication of the troops in the western military region of the Soviet Union was completely paralyzed. The Soviet high command did not understand the war situation and became "deaf" and "blind". After repeated wars and defeats, the Germans marched straight in and soon arrived at the gates of Moscow. In order to change this serious passive situation, the Soviet army quickly adopted a series of measures to strengthen and improve communication, which played an important role in turning defeat into victory.
