翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク field entrenchment ： ウィキペディア英語版 field entrenchment Field entrenchment is the activity of provision of cover and concealment, usually by the Infantry Arm of Service, possibly with assistance from combat engineers or sappers. The entrenched position is intended to be a temporary one, taking maybe a day to create and to be held for no more than a week. However, during World War I these entrenched positions were progressively made more sophisticated over longer periods, leading to their evolution into tactical, operational and strategic stalemates and the emergence of trench warfare.〔Field defences and obstacles, Pamphlet No.2, Part I - All Arms, 1951, Field Engineering and Mine Warfare, The War Office, London〕 ==Notes== 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「field entrenchment」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
