In the middle ages a rose was suspended from the ceiling of a council chamber, pledging all present to secrecy,or sub rosa ,"under the rose".
中世纪的时候，议会大厅里通常会悬挂一朵玫瑰花，表示在这个房间里所商谈的事情都是高度保密的。来自拉丁语的词组sub rosa至今在英语中还表示“保密的”的含义。
While only the team leaders will get the whole kit and caboodle for now, every soldier will get a GPS beacon, alerting the higher-ups to their sub rosa whereabouts.
不过目前只有长官才能得到全套装备，每一个步兵会得到一个GPS信标，来让他们的长官知道自己手底下缄默的小伙子们的下落。
