I'm a little stuck... Click here to teach me more about this clue!

'proposals' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps you can see a link between them that I don't see?

'underwater operations' is the wordplay.
'underwater' becomes 'sub' (as in submarine).
'operations' becomes 'missions' (mission is a kind of operation).
'sub'+'missions'='SUBMISSIONS'

'for' is the link.

Can you help me to learn more?
