1) The document discusses using autonomy and big data to enhance military capabilities. It describes how military platforms could use prior environmental data to achieve greater autonomy.
2) Several challenges for military applications were identified, including operating in GPS-denied environments and dealing with threats. The discussion focused on acquiring and processing environmental data for autonomous vehicles.
3) Two specific challenges were outlined: sourcing big data in difficult, hostile environments with limited resources; and validating data from multiple sources that may be trusted, classified, unvalidated or open/ambiguous. Transforming intelligence using big data is seen as important for the future.
