It was developed by Mr. Prétot, engineer, and Jules-Louis Breton, member of the French National Assembly.〔Gougaud, p.104〕 ==Background== The immobility of the trench warfare characterizing the First World War led to a need for a powerfully armed military engine that would be at the same time protected from enemy fire and could move on the extremely irregular terrain of battlefields. Barbed wire especially posed a considerable threat as it was cheap and easy to install, extremely effective at slowing or stopping an offensive by troops against protected fire, and very difficult to eliminate, even with artillery. Special machines were considered to attempt to eliminate this problem: armoured, armed vehicles, with a capacity to flatten or otherwise eliminate barbed-wire lines.〔Gougaud, p.102〕 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「Breton-Prétot machine」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.
