Purple Pitot...
"Chickenhawk" is a decent book so long as you ignore the fact that Mason borrowed the majority of his account from the experiences of others in his unit. I have a very close friend who shared the cockpit with Mason on more than a few flights as Mason's Aircraft Commander and he has very little good to say about him.
Other excellent books are "BlackHawk Down!", "We were soldiers once and young", "The Ravens", "Shooting at the Moon","Dispatches", "A Soldier Reports", "About Face", "Hamburger Hill"....lots of others....
