I know that question was already asked on this site, but I'm not sure in the answer I read about. So, the question is could passive voice exist without the verb 'be'? Here are examples:
Mission is accomplished.
The usual "mission accomplished" message.
In the first case, we have a passive voice. In second, I believe, too. But which of them is right? I guess both are.
P.S. I read about this that this is called 'middle voice'. And something about verbs we can use in a passive voice without 'be', regardless I would like to get an answer.
