(城堡、要塞或军舰上的)炮位室/炮台暗室:带有厚墙或装甲防护、用于安置火炮或射击的封闭空间;也可泛指装甲掩体。(另有较少见用法指军舰的“炮廓”)
/ˈkeɪsmeɪt/
The soldiers took cover in the casemate.
士兵们躲进了炮位室里掩护。
Built into the fortress wall, the casemate allowed the guns to fire through narrow openings while keeping the crew protected from enemy fire.
炮位室嵌在要塞墙体之中,让火炮能通过狭窄射口射击,同时保护操作人员免受敌方火力攻击。
来自法语 casemate,更早可追溯至意大利语 casamatta(常被解释为“(防御用的)暗室/掩蔽处”一类的构词)。该词在近代军事工程发展中被广泛使用,用来指要塞或军舰上用于防护射击的封闭炮位空间。
