If he was never given the order, how could he have disobeyed it? Your argument reminds me of a joke about a defense lawyer in a rental-car damage case. First, he told the court that his client had never rented the car in question. Second, he told the court that the car was already damaged when his client took possession. Third, he told the court that the car was in perfect condition when his client returned it.
Read what I wrote. Lakin was not ordered to deploy. He disobeyed other orders, one of which was to report to Fort Campbell, Kentucky, not Afghanistan. I apologize if English is your second language.
