PATCH: Personal And Tactical Communication Hardware

At Carroll International—a HUBZone-certified, Service-Disabled Veteran-Owned Small Business (SDVOSB) with over 300 prime contracts since 2016—we're dedicated to delivering mission-critical solutions in secure communications, asset tracking, and tactical mobility. As recipients of the DoW Nunn-Perry Award and official Protégé of General Dynamics Mission Systems, we pride ourselves on forging partnerships that enhance warfighter capabilities and operational resilience. Today, we're excited to announce our new collaboration with Roper Solutions Inc., a U.S.-based innovator in advanced technology, as we integrate their groundbreaking product into our portfolio.

We're thrilled to introduce PATCH "Personal And Tactical Communication Hardware"—a patented,  TRL-9, non-ITAR wearable device that's redefining tactical operations. Designed as a lightweight, waterproof patch that seamlessly attaches to uniforms without adding bulk, PATCH creates an instant, encrypted peer-to-peer mesh network using AES-256 security and low-observable transmissions. Its unique attributes include standalone GNSS geolocation, AI-driven activity and wellness monitoring via built-in accelerometer and gyroscope, and seamless integration with systems like (A)TAK for over-the-horizon communications. 

With a 4.5-mile range on land (10+ miles on water), IP68 ruggedness, and QR-code setup for rapid deployment, PATCH operates in zero-infrastructure environments—perfect for special operations, law enforcement, disaster response, search & rescue, and other expeditionary forces. Proven in high-stakes validations by Naval Special Warfare and LAPD SWAT, PATCH is already empowering teams with secure, resilient, low-profile connectivity. We're actively seeking to add PATCH to our GSA MAS Schedule #47QTCA23D007A (SIN 517312) to streamline federal acquisitions and support our partners' needs.

The Battlefield Challenge: Gaps in Communication and Awareness at the Tactical Edge

In austere and denied environments, as shared by Roper Solutions COO, Co-founder and retired Navy SEAL commander Dana De Coster in our recent podcast interview, military units face persistent "bad movie" scenarios—repeating frustrations from deployments like Iraq between 2005 and 2015. Commanders struggle with incomplete tracking of dispersed teams, including U.S. forces, partner nations, and local allies, due to incompatible systems, security protocols limiting equipment sharing, and reliance on vulnerable ad-hoc open sourced tools.

This fragments the common operating picture, hindering deconfliction across multi-domain operations and leaving critical details—like individual locations, activity levels, and wellness status—in the dark. The impact on safety is profound: without real-time visibility, risks escalate from friendly fire incidents and delayed responses to distress signals, endangering lives and compromising mission success in GPS-denied or electronically contested terrains environments.

PATCH as the Revolutionary Solution

Enter PATCH: A low-viz mesh networking wearable that "maps the gaps" in situational awareness with operator-level BFT, activity monitoring, remote wellness checks & text messaging.

Setup is effortless—User-friendly QR code network setup allows any PATCH to bepart of a PATCH network for instant interoperability. Shake to wake, scan the QR code, follow the prompts in the app, and PATCH creates an instant peer-to-peer mesh network: no third party carriers, no stored data, AES 256-bit encryption. Any PATCH can be paired with a smartphone for in-app texting and ATAK integration, or issued as a standalone low-observable tracking and activity monitoring of each team member. 

Transforming Future Tactical Communications

PATCH's leap-ahead tech resolves capability gaps in a complex multi-domain, multi-partner response, revolutionizing PACE plan resilience and team safety. PATCH is in production and in use by US and Allied forces.
