You're exactly right. The bammy-bots ought to be smart enough to know what they don't know. Set the objectives in clear terms (and stick to them) then leave it up to the professionals who have quite literally made a career out of "implementation" of military objectives.
Of course the fundamental problem is the liberal elitist/fascist mindset - they actually believe they know best for everyone on everything. Scary form of self-aggrandizing mental illness.
