An active SERE kit differs from any other survival or task kit in that it must be concealed on your person ready for deployment, not unloading.
Survival in any form for any environment is an act of prevention and or recovery, best enacted by preparation.
A particular set of tools must be removed from a SERE loadout kit to be applied for field use, forming an independent and “active” deployment carry kit.
An active SERE kit is not a pack or pouch filled with many tools to be carried for universal use. It is a select few tools for a specific purpose such as escape/evasion and is integrated on to the person.
