Adversarial C4ISR Tactics and
China’s investment into C4ISR capabilities is pivotal to the modernization of its People’s Liberation Army (PLA). This architecture integrates satellites for communication, navigation (notably BeiDou), imaging, airborne and maritime sensors (manned aircraft, patrol planes, and UAVs), coastal radars, and advanced ground networks. Enhanced command-and-control nodes and secure communication systems link these components, allowing for the rapid fusion of information from dispersed sensors into an operational picture for commanders and weapons systems.[11],[12]
Beijing has already leveraged its capabilities to enhance missions that impact American interests and regional stability. In the South China Sea and the Taiwan Strait, integrated ISR and command networks allow for ongoing surveillance of naval and aerial assets, enabling the PLA to monitor American allies, direct strike forces, and implement anti-access/area-denial (A2/AD) strategies. Furthermore, space-based systems provide support for long-range targeting and operations, increasing the PLA’s capacity to challenge U.S. military assets and logistics without direct conflict. China’s C4ISR investments extend beyond kinetic modeling to include non-kinetic and gray-zone competition, complicating American military operations and decision-making. These investments enhance signals and imagery collection for intelligence and targeting, empower cyber and electronic-warfare capabilities to disrupt U.S. command and communications, and involve space developments aimed at protecting Chinese assets while challenging American reliance on satellite systems. Additionally, ongoing peacetime surveillance and frequent military operations increase pressure on U.S. and allied forces by raising operational risks and political costs of escalation.[10],[12],[13],[14]
China’s implementation of integrated C4ISR enhances the information landscape and, thus, situational awareness for commanders, refining PLA force precision and coordination and offering alternatives to challenge U.S. dominance in the Indo-Pacific without engaging in direct conflict. This approach has prompted the U.S. to prioritize resilience, adopt distributed command structures such as Joint All-Domain Command and Control (JADC2), fortify communications, and invest in counter-ISR and cyber defense, as information superiority and robust networks are crucial in modern warfare.[14],[15],[16]
Russia has also significantly invested in C4ISR capabilities as part of its military modernization since the early 2000s, focusing on battlefield awareness, long-range targeting, and strategic command. This strategy combines Soviet-era doctrine with modern technologies such as satellite communications, electronic warfare, and advanced reconnaissance drones. Centralized command and rapid data sharing between units are key features, demonstrated in operations in Ukraine, Syria, and along NATO’s borders.[17],[18]
Russia utilizes integrated C4ISR systems in regional conflicts to effectively coordinate its forces and gather intelligence on adversaries. In Ukraine, this includes the use of drones, signal intelligence, and electronic warfare capabilities to detect, track, and disrupt Ukrainian forces. The use of reconnaissance-strike complexes (RSCs) integrates sensor data with long-range strike capabilities, enabling rapid targeting of significant objectives and emphasizing tempo superiority in combat operations. Russia employs its C4ISR assets to observe and challenge NATO and U.S. military operations, utilizing space-based surveillance, electronic intelligence, and cyber capabilities. These tools enable Russia to watch U.S. troop movements, intercept communications, and assess defense systems. Additionally, strategic bombers and submarines conduct patrols near U.S. airspace to gather ISR data. Investments in anti-satellite weapons and counter-C4ISR tools further aim to undermine Western dependency on space and communications in potential conflicts.[18],[19],[20]
Russia’s C4ISR infrastructure is vital to its “information confrontation” strategy, encompassing cyberattacks, disinformation, and electromagnetic warfare. Moscow acknowledges that modern warfare involves not only conventional weaponry but also data. Its capacity to disrupt U.S. forces in Europe through cyber intrusions and GPS spoofing poses a significant threat. In response, the U.S. is bolstering investment in resilient communications, satellite hardening, and rapid ISR integration to mitigate threats.[18],[21]
