Colonel. The Rank at which one slides gracefully from Field Officer to General Staff Officer rank, denoted by the wearing of red tabs on the shirt collar, or service dress lapel, a mega pension, and the relaxed attitude that says "I've commanded my Battalion, got the kids through uni, my pension's safe - from here to retirement, I'm on cruise control".

Not to be confused with the less important (but for God's don't tell them that):Lieutenant Colonel or Half Colonel - normally the CO of a Battalion sized (Major) Unit.

Colonel or Full Colonel is a senior Staff Officer or the CO of an exeptionally large Major Unit such as a training establishment or Depot.
