I understand the regimental system. Unfortunately, too many people warp the concept to be "my regiment".
I did wear a "real" cap badge briefly and felt no differently after a change of location, unit, trade, and badge. Wearing the regimental badge in an infantry or armoured unit is an excellent idea. I simply question the assumption that certain badges have "no history" or an implication that some are inherently more worthwhile in some unquantifiable sense.
