C2 That Keeps Fighting When the Network Goes Dark
Sustaining Command & Control in Denied, Degraded, Intermittent & Limited (DDIL) Environments
Modern adversaries are built to break your communications. Jamming. Cyberattacks. Infrastructure strikes. The question isn’t if comms will fail. It’s whether your team can keep operating when they do. REDCOM ensures the answer is yes.
What Is a DDIL Environment?
A DDIL environment — Denied, Degraded, Intermittent, and Limited — describes any operational condition in which communications are challenged, disrupted, or cut off entirely. Each condition represents a distinct threat spectrum:
- Denied: Complete loss of signal due to jamming, physical obstruction, cyberattack, or infrastructure destruction
- Degraded: Partial signal loss that reduces throughput, increases latency, or introduces packet errors under adversary pressure
- Intermittent: Connectivity that drops unpredictably due to mobility, terrain masking, or deliberate adversary electronic warfare
- Limited: Severely constrained bandwidth that forces hard prioritization of which traffic gets through
DDIL is not a worst-case scenario. It is the baseline condition of modern near-peer conflict.
The Reality of Modern Tactical Communications
Modern warfare has fundamentally reset the communications playing field. In some cases, warfighters may not even be operating from established forward bases. In today’s operational environment, units might be embedded among local populations with a clandestine presence, which means portable, adaptable communications aren’t a luxury. They’re the mission.

At the same time, adversaries have become surgical in how they attack the network. Modern jamming techniques target the top of the communications stack, which is often the most costly and sophisticated IP- and cloud-based technology. Meanwhile, precision strikes and infrastructure attacks eliminate the base layer of host-nation communications. That means most operations today are being executed in the middle layer: raw RF. Comms assets are among the first things taken out. The lesson? Warfighters must be adaptable and capable of operating across any available method of communications.
Most modern tactical communications platforms weren’t built for this reality. They rely on IP networks, cloud infrastructure, and server availability. When the network degrades or disappears — and it will — so does the capability. Software-only solutions are particularly vulnerable: without a server, many lose session state, drop active voice patches, and require manual reconfiguration at the exact moment operators can least afford it.
Many vendors have narrowed themselves to a single technology type, leaving no room to fall back when that technology fails. That’s not a resilience strategy; it’s a single point of failure.
REDCOM sees the full spectrum as a strategic advantage, not a legacy burden. We’ve embraced network-agnostic transport and the concept of infinite interoperability — precisely because contested environments demand them all.
A Layered, Multi-Path Architecture
How REDCOM Solves DDIL
REDCOM’s approach is architectural. Rather than bolting a resilience layer onto a standard platform, Sigma builds multi-path survivability into its core from the ground up. Think of it as a layered communications stack. When one path fails, Sigma lets warfighters rapidly move on to the next.
When the enemy has a killswitch for the network, interoperability becomes a warfighter’s best defense. Sigma can bridge across all these layers with limited operator intervention, maintaining communications across the most optimal path.
Auto-PACE for Automatic Fallback and Resiliency
PACE planning — Primary, Alternate, Contingency, Emergency — is standard doctrine. Executing it manually under fire is not.
When a network path is disrupted, Sigma recognizes the signal loss and re-establishes communication over the next available transport — in the priority order you’ve pre-configured — with minimal downtime or operator input.
Auto-PACE works across every transport Sigma supports: IP, SATCOM, 4G/5G, MANET, RF, and analog.
Countering Electronic Warfare
Electronic warfare is the primary driver of DDIL conditions in near-peer conflict. Frequency jamming, GPS spoofing, and directed RF interference are designed to neutralize fixed-frequency communications. REDCOM addresses this threat at the architecture level, not as an afterthought.
Jam-resistant MANET transport
Instead of relying on fixed-frequency or single-path communications, Sigma can leverage Mobile Ad-Hoc Networks (MANETs) as a transport backbone, trunking two Sigma instances over a resilient mesh that routes around interference automatically.
Software-defined radio integration
REDCOM Sigma can also integrate software-defined radios (SDRs) directly into the network, adding another layer of spectrum agility to the jam-resistance stack. The waveform and encryption are agnostic. If the radio supports RTP, Sigma can use it.
C2 Without the Footprint
The most capable DDIL platform is worthless if your team can’t carry it or set it up in minutes without IT support. REDCOM STRIKE changes that calculus entirely.
STRIKE is a ruggedized Getac X600 Pro laptop running Sigma that unifies IP and RF communications across SATCOM, 4G/5G, MANET, and legacy radio networks. It’s your entire command center in a single device.
Retransmission sites without vehicles
Traditionally, retransmission sites require a vehicle as a power source, tying the site to vehicle-accessible terrain and increasing exposure. With STRIKE, units eliminate the vehicle from the equation. The retransmission node becomes smaller, harder to detect, and survivable in positions no vehicle can reach. In an era when soldiers are operating with a clandestine presence among local populations, that reduction in footprint isn’t just convenient. It’s operationally critical.
Session preservation across power loss
In the event of forced shutdown or power interruption, Sigma preserves full session integrity. Shut the lid, move to the next position, reopen. Every active voice path, patch, and routing configuration is restored exactly as it was. No data loss. No manual reset. No operational pause.
JITC-Certified. Field-Proven. U.S.-Made.
REDCOM Sigma has completed full Interoperability and Cybersecurity certification through DISA’s Joint Interoperability Test Command (JITC) and is on the Approved Products List (APL). Our platforms are TAA-compliant, designed and manufactured in the United States, and deployed across the U.S. Army, Air Force, Marine Corps, and Navy in numerous programs of record.
When mission-critical communications cannot fail, organizations turn to REDCOM.
