A swarm could be particularly effective at this because of its potential to collect big data in real time. Without pause, swarm combatants could relay situation reports faster than any squad leader on a radio. Every soldier may be a sensor, but each swarm com- batant will be a sensor platform with an infallible memory.6 A shot fired by or at a swarm combatant provides a data point Scan Eagle unmanned aerial vehicle designed to provide multiple surveillance, reconnaissance data, that, when aggregated, could help the and battlefield damage assessment missions launches from amphibious dock landing ship USS swarm (or human analysts and operators) Comstock, February 25, 2011 (U.S. Navy/Joseph M.
