Its good and youve given them a nice solid backstory with a reason for them turning.

They still have the air of mystery about them (you havent given away all the story yet). Also by choosing to make them just one company instead of a whole chapter you have chosen to limit them which is good-all to often you see entire chapters that "suddenly turn".

I like it and look forward to seeing more material and hopefully some pictures of finished marines
