In military terminology, a demolition belt is a selected land area sown with explosive charges, mines, and other available obstacles to deny use of the land to enemy operations, and as a protection to friendly troops. There are two types of demolition belt: * A primary demolition belt is a continuous series of obstacles across the whole front, selected by the division or higher commander. The preparation of such a belt is normally a priority engineer task. * A subsidiary demolition belt is a supplement to the primary belt to give depth in front or behind or to protect the flanks. == See also == *Camouflet *Land mine 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Demolition belt」の詳細全文を読む スポンサード リンク
