Succeeding in 21st Century Battle Network Competitions – Success in war is often measured by territory gained and enemies killed. These metrics, however, may not reflect what is really most useful in winning a conflict or military competition. In many cases, disrupting, delaying, or harassing the enemy may be sufficient to achieve one’s most important military objectives. In the short-term, the side using these approaches may be able to gain a temporary advantage toward a larger goal; in the long-term, these approaches may impose significant costs on an enemy in exchange for a relatively small investment.
