The United States Army has announced their plans on using robotic vehicles to aide soldiers in the battlefield and provide medical support. By adapting the technology being used by robots who examine and detonate Improvised Explosive Devices (IEDs), these Unmanned Aerial Vehicles Systems (UAVs) can be used to deliver blood and other medicine while in battle. These UAVs will lessen casualties, whether medics or other soldiers, who have come running to the ailing comrades' sides.
The Army Medical Research and Material Command have also started developing sensors that can monitor the soldiers' vitals and health needs remotely, and these sensors might be installed on the UAVs as well. That means that they will have an idea what exactly the soldier needs at that time, and they will know which one needs to be prioritized in terms of rescuing.
