The key to success in a counterinsurgency environment is not to create more
insurgents than you capture or kill. A stray tank round that kills a family could create dozens of insurgents for a generation. Thus, it is essential to use force as carefully and with as much discrimination as is possible. This is especially important at situations like checkpoints when soldiers must be given the non-lethal tools to protect themselves from possible car bombers without relying upon deadly force. Always consider the long-term effects of operations in a counterinsurgency environment. Killing an insurgent today may be satisfying, but if in doing so you convince all the members of his clan to fight you to the death, you've actually taken three steps backwards.
I'd be happy to discuss the interview, the new Army/Marine Corps "Counterinsurgency" Field Manual, or other topics of interest via this blog when my day job commanding the 1st Battalion 34th Armor allows. Duty First!
