Callsign IR Patch – Infrared Marker for Tactical Identification

High-Visibility Callsign ID for Night Operations

The LOF Defence Callsign IR Patch helps identify individual personnel and team members during low-light, no-light, and night-vision-supported operations. Displaying your callsign on your equipment gives teammates a clear reference when faces, uniforms, and other visual identifiers are difficult to distinguish.

Built using SandStorm Technology™, this patch combines infrared reflectivity with precision laser-cut construction and a low visible-light signature. Mount it to a plate carrier, helmet, sleeve, or pack to keep your callsign positioned where your team needs to see it.

Built for the Modern Battlefield

Matching equipment and limited visibility can make it difficult to tell personnel apart. The Callsign IR Patch provides an additional identification reference under night vision, helping teammates recognize the person behind the gear.

Use callsign markings across your equipment to support consistent identification during training, field exercises, and operational deployments.

SandStorm Technology™ for Maximum Durability

SandStorm Technology™ uses a single-layer film with embedded microprisms to produce a consistent infrared return under night vision. Its construction avoids the layered seams and air gaps found in some conventional reflective materials, helping reduce potential points of failure.

Combined with an abrasion-resistant laminate and precision laser-cut edges, the patch is built to withstand regular handling, equipment contact, and exposure to demanding field conditions.

FAQ

Does the Callsign IR Patch work with night vision devices?

Yes. The IR reflective material returns infrared illumination, making the callsign visible through compatible night vision devices. Visibility depends on illumination, viewing angle, distance, and equipment.

Does the patch produce its own infrared light?

No. This is a passive reflective patch. It reflects infrared illumination rather than generating light and requires no batteries.

Is this patch compliant with NIR standards?

Requirements vary by agency and application. If your unit requires compliance with a specific NIR or infrared identification standard, contact LOF Defence to confirm suitability before ordering.

Will the IR material wear over time?

SandStorm Technology™ is designed for durability, but reflective materials can wear with prolonged use and exposure. Inspect your patch regularly for damage, contamination, or reduced reflectivity.

Can I use this patch during daylight operations?

Yes. The callsign provides a visible marking in daylight, while the infrared material supports identification under night vision. Daylight contrast depends on the patch configuration and lighting conditions.

Is this patch made in Canada?

Yes. LOF Defence Callsign IR Patches are manufactured in-house in Edmonton, Alberta, Canada.
