Got 'Learning to eat soup with a knife' by Nagl, cheap price aswell (I love you amazon!) today, planning to read in the near future.

Nearly finished 'On War' but I am reading through the largely redundant chapters on marches, billets etc, I have decided not to foregoe these chapters because I feel that I should read the whole thing to get an overall perspective, plus I may miss something that relates to the more important parts of the book

Have also been going through John Keegan's 'Intelligence in War', may disagree with him about Clausewitz but it is still a very informative and well put together book.
