System Overview

A Fundamentally Different Approach

The Umbra MSC is a field-tested multispectral camouflage overgarment designed to reduce detection across all major spectral bands. Unlike conventional systems that rely on uniform thermal suppression, the Umbra employs a three-dimensional, non-uniform leaf-based architecture.

This architecture disrupts recognizable human signatures by generating randomized thermal and visual patterns that more closely replicate natural environments — making the operator harder to detect by both human observers and sensor systems.

The system has been validated through five field trials with elements of the Canadian Armed Forces including Canadian Special Operations Forces Command (CANSOFCOM), Department of National Defence (DND), and 1st Battalion Royal Canadian Regiment (1 RCR).

NIR-compliant materials validated through night observation

SWIR

900–2500 nm

Surface structure reduces reflectivity and contrast

MWIR

3–5 µm

Non-uniform thermal architecture disrupts recognizable patterns

LWIR

8–14 µm

Randomized hot/cold pattern reduces silhouette coherence

Validation

Field Test Results

Five independent field trials conducted with Canadian Armed Forces across arctic and temperate environments using ground-based, handheld, and UAS-mounted thermal sensors.

Handheld Thermal Test
Test A — Ground Handheld

HIKMICRO Sensor

Close-range temperate test at ~20ft, 25°C. Human outline not distinguishable from surrounding foliage. Operator blends into vegetated environment.

Arctic Thermal Test
Test B — Arctic Conditions

Thales Sophie Ultima

Ground test at ~200m, −20°C. Human outline not readily distinguishable. Reduced thermal coherence confirmed in extreme cold conditions.

4 Hour Wear Test
Test C — Extended Wear

4 Hour Continuous Wear

Garment tested after 4 hours of continuous wear. Minimal thermal bleed-through confirmed — performance maintained throughout extended operational period.

Aerial Thermal Test Open Terrain
Test D — Aerial / UAS

DJI Thermal — Open Terrain

Drone test at ~400ft altitude, 22°C. Standing individuals clearly visible without system. MCO operator signature approaches background in open terrain.

Aerial Thermal Test Field
Test E — Aerial / UAS

DJI Thermal — Field Environment

Aerial observation over mixed terrain. Reduced signature coherence confirmed. Critical for counter-UAS positioning and overhead sensor threat environments.

Aerial High Altitude Test
Test F — Aerial / High Altitude

DJI Thermal — Altitude Survey

High-altitude aerial survey confirming broad area performance. Operator detection probability reduced across full survey area under aerial thermal observation.

Umbra MSC System
Configuration

Mission-Configurable Architecture

The Umbra MSC is modular by design. Individual leaf tiles can be added or removed to adjust weight, coverage, and thermal performance for mission-specific requirements.

The key performance variable affected by tile density is thermal bleed-through time — higher density delivers longer sustained performance; reduced density provides a lighter, more mobile configuration.
