The Pentagon Wars by Col James Burton was recently re-released for the Kindle. It should be mandatory reading for anyone in the armed services. It's got some stellar first hand insight into Col Boyd's theories and impact, the inner workings of the military-industrial-congressional complex, and how we got where we're at today as a military. Among other things, Col Burton put his entire career and livelihood on the line to ensure the Bradley Fighting Vehicle wouldn't be a coffin on tracks for our ground pounders.
It's been a while, but I remember the HBO movie based on the book being decent.
