Not this
He is a ensign in the navy.
Use this
He is an ensign in the navy.
ensign 读作 /ˈɛnsən/，以元音音素 /ɛ/ 开头，所以不定冠词要用 an 而不是 a；而且表示具体军衔时 ensign 是可数名词，作表语时必须加冠词，因此 a ensign 是错的。
Not this
He is an ensign in the army.
Use this
He is a second lieutenant in the army.
ensign 只表示美国海军或海岸警卫队的少尉，不用于陆军；中文“少尉”不分军种，学习者容易把 ensign 套用到陆军，造成词义误用，陆军少尉应为 second lieutenant。

记法：军舰上的旗和海军少尉都叫 ensign，看见旗就想起少尉。
语域：mixed 常见场景：美国海军/海岸警卫队、军事文件与报道、军衔介绍 作“海军少尉”讲时，多用于美国海军或海岸警卫队的正式场合；作头衔（如 Ensign Smith）时较正式，作普通名词说明身份时中性。日常口语中可能直接称呼姓氏。
以上词语都不与 ensign (/ˈɛnsən/) 押韵。拼写中含 -sign 的单词（sign, assign, design, resign, consign）通常读作 /saɪn/，而 signal 读作 /ˈsɪɡnəl/；ensign 在此读作 /ˈɛnsən/，注意第二音节弱读为 /sən/。
