No, that is not the extension of any logic that I presented. I pointed out the benefit of our stop-move in OIF I and further opined that no leader worth a damn would allow a change of command of a battalion commander or higher while the unit is in harm's way.
"... as is known by everyone with experience in the military, company, battalion, and brigade command are the locations where real life and death decisions are made, especially in wars such as Vietnam and Iraq."
Iraq is far, far different from Vietnam. My experiences are not much different than most of my peers and my unscientific estimate is that 99% of life and death decisions on my last deployment were made by platoon leader and below. The other 1% of life and death decisions were made by company level leadership (CO or XO) and largely were decisions about whether to kill a terrorist now or in 5 minutes.
"The current system is damn near criminal."
I don't know what books you're reading, so I doubt that I will change your mind or address all of your real or imagined concerns. I'll just say that the leadership changes that we were most concerned about were the company level and below and those changes, in my unit, were only made in exceptional cases. The sky is not falling.
