Tactical Communication in 2025
In the evolving landscape of modern warfare, tactical communication is undergoing a profound transformation. Gone are the days when battlefield communication relied solely on radios and voice commands. Today, tactical communication is about delivering real-time data, enabling faster decisions, and supporting multi-domain operations with precision and agility.
As defense agencies worldwide adapt to new threats and technologies, the U.S. Army is leading a strategic shift toward data-centric tactical networks. This blog explores how tactical communication is changing in 2025, based on verified insights from official government sources.
From Radios to Smart Devices: A Tactical Revolution
One of the most significant changes in tactical communication is the move away from traditional radios. Under the Next Generation Command and Control (NGC2) initiative, the U.S. Army is testing the use of Android-based End User Devices (EUDs) to replace legacy radio systems at the battalion level and below.
These smart devices offer a range of capabilities:
- Voice-over-IP (VoIP) for secure voice communication
- GPS tracking for real-time location awareness
- Data transmission for sharing maps, images, and mission updates
The shift was tested during Project Convergence at Fort Irwin, California, where soldiers used these devices to coordinate missions more efficiently. The goal is to reduce the number of radios and batteries soldiers carry while increasing their ability to share information quickly and securely.
This change reflects a broader trend: tactical communication is no longer just about voice, it’s about data delivery. Soldiers need access to real-time intelligence, sensor feeds, and mission-critical updates. Smart devices are becoming the new backbone of battlefield connectivity.
The 30-Month Sprint to Tactical Network Modernization
In August 2025, Lt. Gen. Jeth Rey, Deputy Chief of Staff, G-6, announced a 30-month sprint to modernize the Army’s tactical communication systems. This initiative is part of a larger effort to transform the Army into a data-driven force capable of operating in contested, multi-domain environments.
Key focus areas of the sprint include:
- Artificial Intelligence (AI) and Machine Learning (ML) for predictive analytics and automated decision-making
- Modular Open System Architecture (MOSA) to ensure interoperability across platforms
- Electronic Warfare (EW) integration to counter adversarial signals and protect communications
The modernization effort aims to deliver secure, real-time data to warfighters, replacing legacy systems with agile, scalable networks. Tactical communication is now viewed as a pathway to data, not just a channel for voice transmission.
Lt. Gen. Rey emphasized that the Army must “treat tactical communications as a data delivery system,” enabling commanders and soldiers to make faster, more informed decisions in the field.
Unified Tactical Networks: Enabling the Data-Centric Warfighter
The U.S. Army Signal Corps is playing a critical role in this transformation. In April 2025, the Army Communicator publication outlined efforts to enable the data-centric warfighter through unified tactical networks.
These networks are designed to:
- Support distributed operations across air, land, and cyber domains
- Enable real-time coordination between units and command centers
- Provide secure, resilient communication in contested environments
One of the key tools being deployed is the Android Tactical Assault Kit (ATAK). This software platform offers:
- Real-time mapping and geolocation
- Secure chat and messaging
- Mission planning and coordination tools
ATAK is being used by soldiers to enhance battlefield awareness, streamline communication, and improve operational efficiency. It’s a prime example of how tactical communication is evolving to meet the demands of modern warfare.
Digital Kill Chains and the Integrated Tactical Network (ITN)
Another major development is the implementation of the Integrated Tactical Network (ITN). In 2025, the 1-319th Airborne Field Artillery Regiment successfully transitioned from legacy SINCGARS radios to ITN, marking a significant milestone in the Army’s digital transformation.
ITN supports:
- Digital fire mission execution for faster and more accurate targeting
- Secure waveforms to protect against electronic interference
- Flexible architecture that adapts to different mission requirements
This transition enables the creation of digital kill chains, where sensor data, targeting information, and command decisions are linked in real time. The result is a faster, more lethal response to threats powered by integrated tactical communication.
The ITN also supports mission command on the move, allowing commanders to maintain situational awareness and control even in dynamic, high-risk environments.
Embracing Cybersecurity in Data-Centric Tactical Networks
As the U.S. Army shifts toward data-centric tactical communication, it prioritizes securing these advanced networks against evolving threats. Army cybersecurity teams actively implement robust defenses such as end-to-end encryption, which protects data from interception during transmission. They continuously monitor networks using AI-powered tools that detect and respond to cyberattacks in real time. By employing machine learning algorithms, the Army identifies unusual patterns and potential breaches faster than ever before, enabling proactive defense.
The Army also incorporates adaptive threat detection systems that evolve based on emerging risks, ensuring networks remain resilient even in highly contested environments. Soldiers receive regular training to recognize and respond to cyber threats, strengthening overall operational security. Network architects design tactical communication systems with built-in redundancy and fail-safes to maintain functionality despite attacks or hardware failures.
By focusing on cybersecurity, the Army ensures that sensitive battlefield data, such as troop movements, mission plans, and targeting information, remains confidential and accurate. This focus builds warfighters’ trust in the new communication platforms, encouraging widespread adoption. Ultimately, securing data-centric networks empowers soldiers to make faster, more informed decisions without fear of compromise, enhancing mission success in complex, multi-domain operations.
Why Tactical Communication Matters More Than Ever
The changes in tactical communication are more than just technical upgrades; they represent a fundamental shift in how modern militaries operate. In a world where threats are fast, complex, and multi-dimensional, communication systems must be just as agile.
Here’s why tactical communication is critical in 2025:
- Speed: Real-time data enables faster decision-making and response
- Precision: Integrated systems improve targeting accuracy and mission execution
- Resilience: Secure networks protect against cyber and electronic threats
- Interoperability: Modular systems ensure compatibility across platforms and allies
Whether it’s coordinating drone swarms, managing cyber defenses, or supporting joint operations, tactical communication is becoming the backbone of modern warfare.
Challenges and Opportunities Ahead
While the progress is impressive, challenges remain. Integrating new technologies into legacy systems, training personnel, and ensuring cybersecurity are ongoing concerns. However, the opportunities far outweigh the risks.
Emerging technologies like 5G, edge computing, and quantum encryption are expected to further enhance tactical communication in the coming years. These innovations will enable even faster data transmission, more secure networks, and smarter battlefield coordination.
Additionally, partnerships with industry leaders and academic institutions are helping the military stay ahead of the curve. Collaborative research and development are driving innovation in areas like AI-driven command systems, autonomous communication nodes, and adaptive signal processing.
Final Thoughts: Tactical Communication as a Strategic Advantage
In 2025, tactical communication is no longer just a support function; it’s a strategic advantage. The ability to deliver secure, real-time data across domains is transforming how missions are planned, executed, and evaluated.
The U.S. Army’s commitment to modernization, combined with cutting-edge technologies and unified networks, is setting a new standard for battlefield communication. As other nations follow suit, tactical communication will continue to evolve, shaping the future of defense operations worldwide.
For defense professionals, technology providers, and policymakers, understanding these changes is essential. Tactical communication is not just about connecting people; it’s about connecting decisions, actions, and outcomes in the most efficient way possible.
