ok, first and foremost: this will be littered with potential SPOILERS, so read at your own risk.
I have just finished the first story: Rules of Engagement. At the end of the story, it turns out that the last engagement was a full scale mock battle (although it is not explained how deaths and hits with, say, field artillery were accounted for). Have a few questions:
1) in the first part of the story, Engagement 94. Cptn Remus of the Ultramarines calls himself, and his 4th Company, traitors. But they were fighting as Ultramarines against the Death Guard. So why would the Ultramarines be considered traitors?
2) in Engagement 228, the 4th fights the Salamanders. Was this a mocked up practice battle as well? And if so, when was it ever mentioned before that the Salamanders might be suspect of turning traitor?
I dunno, the only part of the story that seemed to make any sense is when the it is revealed that the last engagement was a full scale mock battle of what if Horus invaded Macragge. Other than that, I guess I just didnt really 'get it'.
Any illumination would be appreciated.
