The experience of the 101st Airborne around Eindhoven not only provides a different lens through which to examine the Market Garden story, it also highlights the importance of placing rear area security at the forefront of planning considerations; particularly as we must expect our adversaries will aim to sever vulnerable lines of supply. The 101st Airborne experience raises a number of issues worthy of further consideration by contemporary planners at all levels of command. Overall, planners must consciously consider rear area security as an active combat operation in a continuously contested environment, thus avoiding static conceptions of this vital work.
