wise man. the 'indoc' really starts to kick in at O-4, seeing that most 0-4s will be considered the XO (exec. officer) at battalion level (nomenclature depends on org). in other words, that's when the officers really get out beyond the company level and really get to see the man-behind-the-curtain as it were. Once a full-bird gets his star, give him command of whatever MAJCOM, COCOM, or whatever line he's in for a year then send him packing. metrics can be pulled as well to see how these commanders (admins) are developing and implementing policy, so I think their tenure should be based on that, similar to how I think teachers' efficacy should be 'measured'
