In the military, one's mandate is to follow the commands (and sometimes the countermands) of the officers. Doing their bidding is not particularly commendable—it's simply mandatory. The Latin verb mandare, meaning "to entrust" or "to order," is the authority behind countermand. It's also behind the words [mandate](https://www.merriam-webster.com/dictionary/mandate), [command](https://www.merriam-webster.com/dictionary/command), [demand](https://www.merriam-webster.com/dictionary/demand), [commend](https://www.merriam-webster.com/dictionary/commend) (which can mean "to entrust" as well as "to praise"), and [mandatory](https://www.merriam-webster.com/dictionary/mandatory). Countermand came to English via Anglo French, where the prefix cuntre- ("against") was combined with the verb mander ("to command"). It has been a part of English since the 1400s.
