下面的翻译对吗？merchant navy是商业海军吗？

鲍罗目前38岁了并且从1968年他大学毕业以来加入了电子工业，后来他参加了商业海军。

海军也能做交易？此外，原翻译也紧急失误！

merchant navy：（英式英语）商船，商船队；全部商船队船员

Paul is 38 years old and has been involved in the electronics industry since 1968 when he graduated and went into the merchant navy.

【翻译】保罗今年38岁，自1968年毕业后进入商船队以来，一直从事电子行业。
