the bag we are developing, whether it be termed BOB or SAR, or whatever, needs to be elegant just the right items in the appropriate quantities - squarely in the goldilocks zone of just right. As Montanero says, it has to be adjusted for the environment and prevailing conditions - a continual process.

For me, the great thing about SAR was that, from time to time, one was called out to do unreasonable things quickly and effectively at random, unforeseen times. In that situation, you find out fairly soon what really works dependably and what is essential. In mt estimation, the main difference between SAR gear and BOB gear would be he specialized communication items and specialized medical items commonly found in SAR packs. We all agree that actual use of critical items is essential (and besides, it's fun!).
