Let me give you my experience with issued berets... sometimes you have to take whatever they have in stock at the time that you are there for your initial issue... in my case, that meant a beret that was a full inch larger than what I required. You can well imagine what that looked like. I tried every possible way of replacing it to no avail. I finally was able to get a new one when I got my DEUs (which I got despite not being in for a year for reasons controlled by my unit).
Actually, before my DEU one arrived, I replaced it with one from the PPCLI kit shop which i was not allowed to wear on course because it was a belgian beret and not an issued beret. So, sometimes nothing has to happen to a beret for a member to want to replace it.
