The Event: I suppose the best way to begin this review is to explain that S.E.R.E. Performance offers a multitude of different challenges and events. Their “Basic” is the baseline and starting point for everyone who wants a gut-check and a lesson in survival. It then ascends from Basic to Advanced, Elite, and then Extreme. “Only four levels?” – You wonder? Nay, nay. This includes four separate facets of Advanced. They are: Urban, Jungle, Desert, and Maritime. The idea is to complete each level before moving on to the next. Now before I go way off into the deep-end, let me be clear that this is a review of their initial challenge; Washington D.C. Basic Class 001B. We were affectionately dubbed “The Frozen Chosin Few” after the Marines that fought in the Chosin Reservoir in Korean War.
