I agree that we shouldn’t expect to hear Marine generals complaining in this case if they were overridden. Especially if the positive outcome reports hold true.
On the other hand, if they actually bought into the argument to halt the attack, rather than simply complied with its imposition, I don’t know why they wouldn’t profess their support. Especially in light of contrary reports.
You make a good point, Marine support of the cease-fire was of the grumble-grumble variety. That may be partly due to their resentment of even comment on their offensive from CentCom. Marines rightfully think they know best when the shootin' starts.
