{{B}}High-Tech Warfare (战争){{/B}}
Today, high-tech warfare is no longer an abstract concept, but a real issue. Technology{{U}} (51) {{/U}}tactics, sociology, and the development of weaponry (武器). It also causes the changes in battles. Then what are the new characteristics of modern battles{{U}} (52) {{/U}}by the application of high technologies?
High-tech warfare naturally includes high technology. In modern battles, a single kind of weapon can hardly be{{U}} (53) {{/U}}. Various weaponry, such as intelligence detection and information processing, should{{U}} (54) {{/U}}well with each other. Aerial (航空的) weaponry becomes the main force in battles in the sky. Precision homing (精确自导) weaponry like cruise missiles and Missiles{{U}} (55) {{/U}}satellite homing systems becomes the main attack weapons.
Battle control systems play a dominant role. Various weapons and logistics (后勤) systems are{{U}} (56) {{/U}}into a comprehensive framework, centrally representing the modern high-tech weaponry. Depending on various{{U}} (57) {{/U}}equipment and means in electronic warfare, our army will not be passively beaten.{{U}} (58) {{/U}}the battlefield, high-tech warfare has created a type of non-linear (非线性的) chaos. Because of the use of long-range precision weaponry, the opposite parties in warfare can't "touch" or "see" each other, and distance is no longer the decisive factor affecting the{{U}} (59) {{/U}}of battles. It is hard to clearly define the lines between the frontier and the rear, as well as attack and defense. The traditional three-dimensional air-sea battlefield will be{{U}} (60) {{/U}}by the multi-dimensional battlefield composed of air, sea, magnetic, electrical and information battlefields. No large-scale movements can be conducted{{U}} (61) {{/U}}.
Because modern weaponry systems are closely related to chains of demand and communication and electronic technology, the parties{{U}} (62) {{/U}}have to pay attention to the usufruct (使用权) and control of electromagnetic frequency spectrum. So electronic warfare becomes{{U}} (63) {{/U}}important and the necessary guarantee of victory. Whatever{{U}} (64) {{/U}}warfare goes to and whatever cloak (伪装) it wears, it always violates peace and brings the world bloodshed (流血). Most people think of high technology as a{{U}} (65) {{/U}}to enhance their lives, and they don't wish it to be used to destroy lives.
