渡河作战历来是一项十分艰巨的任务。到了近代,随着军事科技的发展,装备在复杂化、现代化的同时,也实现了“重型化”,一辆坦克竟然有几十吨重,渡河更成了难上加难的事。于是,渡桥便成为双方斗争的一个焦点,一方要竭力保证桥梁畅通,以利调兵和运送物资,一方则要千方百计地破坏桥梁,以便打乱对方的行动计划。渡河作战上升为军事科学中一个专门的学科,利用谋略保护桥梁也受到人们越来越多的重视。 Cross-river fighting has always been a very arduous task. In the modern era, with the development of military science and technology, while the equipment was being complicated and modernized, “heavy equipment” was also realized. As a result, a tank of tens of tons was heavy and crossing the river was even more difficult. As a result, the crossing bridge has become a focus of the struggle between the two sides. One side must make every effort to ensure the smooth flow of bridges, facilitate the transfer of troops and the delivery of materials, and one side must do everything possible to destroy the bridges so as to disrupt the other side's plan of action. The cross-river operation has risen to a special discipline in the military science. The use of strategies to protect bridges has also drawn increasing attention from people.
