In Februari 2016 I have done the 7-day close protection course of Backup Concept. Retsan was my/ our trainer. Retsan is serious,
calm, restrained but also enthusiast and a spirited trainer. The 7-day training course has been intense but also educational. Retsan
knew how to train the group effectively. For me it was working well. I had not one boring moment or a moment that I lost my
attention. Even at the practical exercises Retsan was a good coach and attendant. He is working hard and constantly sharing his
knowledge.
