Yeah I question what we would do if and when we end up in another Afghan / Bosnia / what ever scenario where we need to rotate BG's in and out every six months if we aren't in a symmetrical structure. Is that more likely than 1 CMBG being required to fight as a Bde in Europe? I'd argue yes.What I found most interesting about this video was that Australia originally had a Heavy Mechanized Brigade, a Medium Weight Motorized Brigade, and a Light Brigade.
They then switched to Mixed Brigade Groups because they were unable to properly sustain a single brigade for long periods of time in Iraq.
Essentially they built the Canadian model which was the CMBG as stated by @Infanteer. All Mid weight+. One unit regenerating, the next working up, and the third on deployment. And here some of us are advocating doing what they had before the change with one Brigade focused as a Heavy Mechanized one Middle Weight and the last Mid-Light forces.
