From Counterinsurgency by David Kilcullen, Australian Army:
Before Motaain, I carried typical Infantry commander's webbing -- lots of navigational equipment, maps, and orders and plans kit, as well as minimal ammunition, water, and first aid equipment. I wore issue belt webbing but supplemented this with British-issue Northern Ireland chest webbing when on patrol, with extra water and ammunition. Many people who wore chest or vest webbing in firefights, including Motaain, came away wanting to ditch it and revert to the issue belt webbing. This was because the chest webbing, by placing the pouches directly below your chest, lifts you an extra ten centimeters or so off the ground. This sounds like a miniscule amount, but with someone shooting at you, it feels enormous. With belt webbing, it is the pouches that are lifted off the ground, while you can hug the earth to your heart's content. After Motaain, I wore the lightest possible belt kit, with ammunition, water, and large amounts of medical kit only. My commander's kit and minimal survival equipment I stuffed into my pockets. I slept out many nights in the jungle with only this equipment, suffering no significant inconvenience. The lesson here, again, is that we are killing ourselves with comfort and convenience -- a little more austerity and a willingness to suffer discomfort in order to better kill the enemy would be well worthwhile.
