The risk of observation is always a threat. Armed Forces around the world are facing all different kinds of challenges when performing in overseas deployments. COBS CT – Counter Observation Barrier Screen – Counter Terrorist – is a totally new concept in reducing the threat from observation and attack against your deployed forces, embassies and airfields.

But also, it means that you can rely on our dedication and willingness to provide our entire knowledge and know-how for improving your operations. That’s what we call a true commiment.


Military forces and special operations forces deployed overseas are vulnerable and have to face many different challenges. To perform and achieve mission success, protection of people and equipment are of vital importance. Saab offers that kind of protection – protection against ballistic penetration, counter barrier systems and portable shelters that provide defence against AP ammunition, RPG and vehicle attacks, as well as protection from heat build-up for vehicles, ammunition and personnel.

Competent and robust

COBS CT is a concept designed to reduce threats from observation and attack against deployed forces and facilities. The system reduces visibility into critical infrastructure and effectively and consistently disrupts or pre-detonates RPGs and other similar weapons. COBS CT is an extremely robust system designed for continuous exposure to the environment for many years without removal.

The COBS CT incorporates a steel mesh screen that disrupts or prematurely detonates rocket-propelled grenades and similar weapons. The CT screen also prevents personnel entry and will even stop vehicles driven into the screen.

Cable Vehicle Barrier option

To stop attacks from light to medium vehicles, the COBS CT can be added with a Cable Vehicle Barrier with the ability to stop vehicles up to 3 tons GVM at 60 kph (37 mph). The system can be upgraded for protection against heavier vehicles. The COBS CVB uses unique, low-cost, steel energy absorbers that stop vehicle attackers dead on the line of the ...?

In use

Saab's Signature Management product range currently has a customer base of more than 50 countries worldwide.

These customer relations have been built up during more than 50 years of dedicated development in camouflage and deception.

Technical specification


COBS CT is a movable and reusable concept for reducing the threat from observation and attack against deployed forces or facilities. COBS CT is a multispectral screening system obstructing observation in the visual, near infrared and thermal infrared wavebands. COBS CT protects against observation, indirect fire weapon direction and direct fire weapons aiming. The steel mesh CT screen is effective in disrupting or prematurely detonating rocket propelled grenades and similar shoulder-launched HE and HEAT missiles.

COBS CT is a rapid-deployment screening fence which utilises steel support posts between which are tensioned Saab Shadecam multispectral screens. The Shadecam, which comes with a 3-dimensional camouflage garnishing, has a very low visibility through the screen in the relevant wavebands.

The COBS CT support posts, which can incorporate a folding mechanism, are mounted on and braced to a flexible foundation system which can utilise steel screw piles for rapid installation, or conventional concrete foundation rafts for ground unsuitable for piling. The steel mesh CT also is effective in preventing intrusion by persons with only hand wire cutters. Both the Shadecam and CT screens can be quickly replaced if damaged by hostile attack. An optional Cable Vehicle Barrier is available for sections that are vulnerable to vehicle attack.

Performance and Signature Management Properties

  • Visual/near infrared. The Shadecam will reduce visibility through the COBS CT by over 90%, and camouflage garnishment can be matched to the surrounding or regional background environment. Visibility outwards from behind the COBS CT is effective from a distance up to approximately 1 meter.
  • Thermal infrared. The thermal transmission of the Shadecam is less than 10%, which is very effective against smart weapons with thermal infrared target acquisition.
  • Counter RPG. The COBS CT screen has been shown in trials to disrupt or detonate incoming shoulder launched RPG:s.
  • Cable Vehicle Barrier. COBS CVB System has been trialled using towed vehicle crash test methods, and has successfully stopped both light (1.5 ton vehicles), and medium commercial (3.0 ton) vehicles within 2 meters of the barrier line at 90 degrees impact angle. The Cable Vehicle Barrier can be upgraded to stop 6.5 ton vehicles at speeds up to 60 km/h.

Physical properties

Nominal COBS dimensions 3 meters height by 10 meters between support posts
Normal maximum wind loading 127 kph/68 knots/35 m/s (thunderstorm gust load)
