Difference between Unity's [Command] and [Server]

Question

[Command] and [Server] functions both run on the server and can also be called by a local player but what is the difference between them?

I'm not 100% sure myself, but I do know that [COMMAND] attribute is only for use on PLAYER controlled objects. That might be something to do with it (I'm also learning Unity Network gaming ~gradually~ at the moment :] — Big T Larrity, Commented Nov 22, 2018 at 12:52

They actually do quite different things according to the documentation:

[Command] functions are invoked on the player GameObject associated with a connection

A [Server] method returns immediately if NetworkServer.active is not true, and generates a warning on the console

But be sure to be mindful of the comment by Draco18s:

\$\begingroup\$ I don't think it matters who or what calls a [Server] attribute. The way I understand it is that you wanna use the [Server] attribute for any function that absolutely has to be connected to the server. \$\endgroup\$
