I think that within the field of maneuver warfare, the current generation of officers is not dogmatic and inflexible. When it comes to a mechanized shootout in a desert somewhere they're quick thinking, creative and downright devious. There is no other way to win those simulations, because if you follow some scripted playbook the "red team" will hand you your head. There's nothing like that for COIN, Stability Operations, Peace Enforcement, etc. So there's room to just settle in and turn off the brain - dogmatism requires a certain degree of complacency in order to thrive. You can't be complacent against a thinking, breathing opponent who wants to win, because that opponent will come up with a way to beat the pants off you. When that starts showing up in your fitness reports it starts impacting careers and that gets noticed.
