Smegma Crazies appear to be former military personnel. They wear uniforms, jumpsuits, kangaroo hides and masks. The masks are military-issue insulated facemasks. I found a place that sells them. They're US$10. To request one, just e-mail me.
The uniforms that the SC's wear look like brown or khaki jumpsuits. I have not been able to identify them, but they are most likely Australian tanker coveralls. The SC who is lit on fire by Max appears to be wearing either one of these coveralls or perhaps a P-37 uniform.
