Not really in the "study guide" vein, but had to recommend a great book I have just finished reading to you guys..
"In the Company of Heroes" by Michael Durant (co-written by Steven Hartov)
If the name rings a bell, Mike is the US Army Blackhawk pilot shotdown and captured during a battle in Mogadishu Somalia, recently made famous in the movie "Blackhawk Down"
Excellent read, an amazing guy, also tells of his flying career in the US Army, he also saw action in Panama and Desert Storm.
Read the book "Blackhawk Down" first if you haven't already, so you get an idea of the battle itself. It's a great read also and is called a "treasured diary' by the soldiers actually involved in the battle.
In his book, Mike Durant finally reveals details of some horrific incidents that happened to him and his fellow crew that weren't in the book and certainly aren't in the movie!
Terrible tale, but worth reading, it tells the tale from the aviators point of view and you come away feeling positive about it all if that's possible, by his wisdom, that can only come from a helicopter pilot!!
