C2 Defender / 4×4 / Mast-mounted multisensor & radar head
Sky is not the limit.
But we are.
REB Defence builds the sensors that see a drone, the effectors that stop it and the command layer that ties them together — designed, engineered and manufactured in Slovakia.

to the operator
Detect. Identify. Defeat. Coordinate.
A drone is only a problem for as long as nobody has seen it. Our systems close that gap in one chain — and every link in the chain is ours.
See it first
In-house radar out to 48 km, RF monitoring from 20 MHz to 12 GHz, and passive acoustic nodes that hear what radar and RF cannot — including drones flown on a fibre-optic tether.
Know what it is
Real-time protocol decoding locates the drone, the pilot and the home point. Multisensor PTZ and thermal imaging confirm the target by eye before anyone acts.
Take it out of the fight
Full-spectrum, directional or selective jamming — including frequency-hopping links — from the vehicle or from a rifle in an operator's hands. Selective, so the spectrum you depend on keeps working.
Move as one
C4TAK carries the same picture to every authorised participant, filtered by role, so the team acts on information instead of drowning in it.

We are not a systems integrator.
Our hardware and our signal-processing software are developed in-house — from RF spectrum analysers to rapidly deployable effectors, from the radar front end to the operator console. Nothing central to the system is somebody else's black box.
That end-to-end control is the whole point. When an adversary changes tactic — a new frequency-hopping scheme, a fibre-tethered drone, a swarm profile — the answer is a firmware release, not a procurement cycle. We answer in days and weeks, not years.
Six systems. One architecture.
Each one works alone. Together they are a single sensor-to-effector chain around whatever you have to protect.

C2 Defender
Mobile command post and multi-domain fusion node. Radar, RF, electro-optics, acoustics and UAV feeds converge into one picture.

ADP
Handheld counter-UAS jammer, 400–6000 MHz, extendable to 12 GHz. Directional and spatial effect from one system.

AcuSync
Hears UAS and small-arms fire on eight microphones, names the threat and points at it — without transmitting a detection signal of its own.

C2 Minions
Four rugged pan-tilt-zoom cameras in transport cases. Live feed straight to C2 Defender, no operator at the position.

I2 Defender
Compact unmanned aircraft launched on a sensor cue. Closes the distance, identifies what it finds and stays with it using Lock2Trace.

C4TAK
Puts the fusion picture on the team's devices. Positions, tasks, hazards and sensor alerts, disseminated by role.
A single sensor is a single point of failure.
High-value targets — government buildings, critical infrastructure, a moving principal, a forward position — need detection, identification and effect at different ranges and by different physics. One sensor is a single point of failure.
On site or on the move
- Ad-hoc networked passive RF detection
- Undetectable radar, safe for populated areas
- Multisensor visual confirmation and tracking
- Passive acoustic nodes where RF and radar go blind
Effect, under authority
- Automatic engagement cued by C2 Defender
- Handheld ADP for the dismounted team
- Airborne identification and pursuit of a cued track
- Integration with customer sensors and networks
Built for the people who have to hold ground.
Forward positions, convoy overwatch, mobile command and force protection.
Principals in transit and at residence, ministries, embassies.
Energy, water, transport hubs, airfields and strategic facilities.
Stadiums, squares and festivals with no permanent infrastructure.
