When evening came, the men assembled at the edge of the forest. Uncertainty and doubt behind, each man understood the importance of his personal mission. A mistake would throw every life into danger and at some point their presence would be detected. Each man stood at the brink of a private nightmare. Discovery was inevitable, however, and the consequences would be deadly for some. MacMahon, a solitary figure dressed in grey and shadowed by grief, coughed softly. The men lifted their worn faces to their Captain.
Common nouns = concrete nouns...? ; men, forest, figure, faces, grey.
Adverbs - deadly, softly...and after that I can only find adverbials =s
EDIT:
"The gold dog", "the blue man" and "motorway crash". You could take blue man, gold dog and motorway crash as noun phrases. Makes things easier to understand in my eyes.
