I think the special forces suit uses the same leg pauldrons as the security suit. Even the belt area matches the security suit. Guess it goes to earthgov for having similar uniforms amiright?
The three rows of straps around the waist look similar to MOLLE straps, used in modern military gear to attach pouches and so on. Nice to see a bit of realism in a world of futuristic glowing armors, plasma cutters and rocket space boots =)
