With the increasing maturity and reliability of artificial intelligence algorithms and high-speed computers, the concept of C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance) on future battlefields will be streamlined into the SNAI concept (Sensors, Networks, and Artificial Intelligence).

Currently, C4ISR is evolving into MCSNAIPMT:
-
Command and Control: The U.S. Army has integrated “Command” and “Control” into “Mission Control” (MC).
-
Communications and Computers: Through the “Sensor Open System Architecture” (SOSA) project and DARPA’s “Collaborative Operations in Denied Environments” (CODE) project, “Computers” and “Communications” are gradually being integrated into “Sensors and Networks” (SN)❶.
-
Intelligence: “Intelligence” is being replaced by “Artificial Intelligence” (AI).
-
Surveillance: The latest “Reaper” and “Global Hawk” drones have transformed “Surveillance” into “Persistent Monitoring” (PM).
-
Reconnaissance: DARPA’s latest version of the “Target Recognition and Adjustment in Competitive Environments” (TRACE) project is transforming “Reconnaissance” into “Targeting” (T).
However, MCSNAIPMT is only a transitional state. As artificial intelligence decision algorithms continue to develop, “Mission Control” (MC), “Persistent Monitoring” (PM), and “Targeting” (T) will merge into “Artificial Intelligence” (AI). “Computers” and “Communications” are becoming part of “Sensors and Networks” (SN). Ultimately, what will emerge is SNAI: Sensors, Networks, and Artificial Intelligence.
Note
❶ In the near future, each sensor will be integrated with high-speed computers and artificial intelligence algorithms, capable of processing and analyzing collected data on-site. Therefore, the “Computer” function will gradually be integrated into the “Sensor”.
Shesheng has spoken
① The network information system in the age of artificial intelligence mainly consists of three elements: sensors, networks, and artificial intelligence. Sensors must operate using the electromagnetic spectrum, networks must be built on reliable spectrum access, and the core of artificial intelligence lies in algorithms. Based on this, it can be inferred that electromagnetic spectrum warfare and algorithm warfare will become two dominant forms of combat on the battlefield in the age of artificial intelligence.
