aide-de-camp

/ˌˈeɪd də ˌkæmp/

An aide-de-camp is a military officer who assists another officer with more seniority. An aide-de-camp is a military assistant.

Many English words come from the military, and many others come from French. This word comes from both, as it's a French term for a military assistant. Just like assistants in other fields, the aide-de-camp will provide the senior officer with whatever is needed. This term also gets a fair amount of work as a general term for an assistant to a powerful person in any organization. Any supervisor or leader may have an aide-de-camp who helps them out.
