The SERE knife we are doing got started when several Air Force SERE instructors asked us to build a specific knife for them.
The school we teach in South America encompasses part of the SERE philosophy / training. We don't teach Resistance or Escape, but we do teach the Survive and part of the Evade portion since the two go together in many ways.
Travel to 3rd World countries is not the reason for a SERE program. SERE is designed for the military professional operating in various environments around the world, however the SERE principles can be used for anyone. We suggest that anyone who travels to foreign countries study such a program in case of kidnap or other things that can happen to you. Hell, that can even happen here in the United States, so learning about SERE can be nothing but good.
