The man with no face in the story could be a variety of things. It could be an allegorical figure, representing the facelessness of society or the anonymity that people can feel. It might also be a product of someone's imagination within the story, perhaps a hallucination or a creation of a disturbed mind. Without more details about the story, it's hard to say exactly who he is.
I'm not sure. It depends on the specific context and the source of the story. Sometimes it could be based on real events, but with some fictional elements added.
Courage makes a man a man of action in a true story. A man who has the guts to face difficult situations, like firefighters running into burning buildings. They don't think twice about their own safety when there are lives to be saved.
I don't think so. Usually, such works are imaginative constructs rather than drawn from actual happenings. There's no indication that 'A Man of Action' has a true story behind it.
I'm not sure specifically who the man is without more context about this 'the man with half a face story'. It could be a fictional character created for a particular horror, mystery or psychological story.
Action Man's story often involves adventure. He might be sent to explore an ancient temple filled with traps. He uses his intelligence to figure out how to avoid the traps. For example, he notices a pattern in the floor tiles that indicates where the hidden pits are. He then moves carefully through the temple, facing off against guardians. His physical strength and combat skills help him overcome the guardians and he might find a valuable artifact in the temple.
