You cannot improve the morale of the force by just changing hats. He probably saw a group of barrel chested, chisel faced, steely eyed warriors ready to take on and defeat this nation's enemies. In other words, all that's wrong with today's army. The Korean War Rangers just changed their Era Monument at the Ranger Memorial to honor the beret and what it means to Ranger history and the Army as worriers. Though I don't have a dog in this fight, I'm sorry to see this snap decision based on pseudo-psychology that giving somebody something of value make one valuable.
Hard work is what made the beret valuable.
