Everything is completely explained in the scenario itself.
The text below is also displayed in the 'Hints' section at the 'Objectives' banner, but I just want to make sure that people do see it, so everyone's aware of it's existence ;) some people don't bother to open the 'Objectives' banner during the gameplay and this way they won't read it ;). It's important to me if you read this though:
