Furtivité, le camouflage haute technologie (JDef)


2 juin 2015 Journal de la Défense (#JDef)

 

Systèmes de vision nocturne, par infrarouge ou de détection radar… la haute technologie est au cœur des opérations militaires modernes. Qu’elles opèrent au sol, sur l’eau ou en l’air, nos armées utilisent tous les jours ces moyens pour détecter et tromper l’adversaire. C’est ce camouflage moderne que l’on appelle la furtivité.

Ce mois-ci, le Journal de la Défense (#JDef) vous emmène au cœur de ces systèmes innovants, à la rencontre de ces spécialistes de la dissimulation.

New camo for Nigerian armed forces

 

05 August 2014 by Oscar Nkala - defenceWeb

 

The Nigerian Army says the service will soon get a new camouflage which will make the troops look 'smarter' and more distinguishable from impostors following recent incidents in which civilians and Boko Haram militant group members were arrested for committing crimes while wearing security services camouflage attire.

 

All three wings of the Nigerian Defence Forces - army, navy and air force - have over the past few years been caught up in extortion and bribery scams in which tricksters in full military fatigues posed as recruiting officers and were paid millions by would-be soldiers.

 

The defence and police services have also suffered battlefield casualties to Boko Haram militants who attacked them while wearing camouflage attire identical to theirs.

 

Addressing soldiers of the 149 Battalion at its Ojo Cantonment in Lagos, Chief of Nigerian Army Staff Lieutenant General Kenneth Minimah said all officers will soon be outfitted with new sets of uniforms which the defence ministry hopes will differentiate them from impostors. Minimah said the army will now produce the uniforms.

 

“The Nigerian Army has decided to change the camouflage uniform of the service. We have also decided to make it ourselves so that it will have a uniform look. We will not allow anybody to make them for us. They are currently being made at the Nigerian Army Tailoring Department at Yaba, Lagos State. It will make us look smarter and better,” he said.

 

Previously, all security services attire and camouflage was tailored by private companies contracted by the respective ministries. Criminal groups including armed carjackers and bank robbers took advantage of the relatively easy access to security services attire and often wear fatigues belonging to the army, navy, air force, police, immigration and other public inspectorate services while committing crimes.

 

The change of uniform comes against a backdrop of rising incidents in which small military units have been wiped out by Boko Haram militants wearing identical uniforms and driving vehicles painted in services camouflage in war-zones in the restive north.

 

Minimah warned disgruntled soldiers against using social networks to spread “falsehoods” about alleged dire conditions in the service and information about military equipment and operations in the three war-torn northern states.

 

“One trend that is also dangerous to the service we all seem to cherish is the misuse of the social media. I urge you to be careful of social media. Some of you like to use Facebook, Twitter and others to report the Army as if you are not a member.

 

"What you do not know is you are undoing a system you are part of. You can twit on social issues. Do not twit about our locations, equipment, weapons and ammunition. I hope you did not come in to undo the system," he said.

 

The warning follows revelations from disgruntled soldiers who have taken to social media to voice their frustrations in a dossier of complaints which includes the army's use of poor and defective equipment, lack of reliable re-supply lines, long-duration non-payment of salaries, lack of motivation and lack of operational and force protection vehicles among the reasons for high casualties as the army appears to be losing the war against Boko Haram in the north.

 

The defence ministry has also threatened to prosecute all officers involved in spreading the information, which the government views as damaging to the local credibility and international standing of the Nigerian Army.

Electronic Weapons: Thermals Baffled By The Nemesis

 

 

February 18, 2014: Strategy Page

 

There’s a new camouflage suit available (the “Nemesis”) for snipers or troops up against an opponent using thermal imaging. Nemesis breaks up the viewable (via a thermal imager) heat the wearer gives off and presents, to the thermal imager, a blob more than an easily identifiable image of a person. This limits the range at which the thermal imaging user can be sure it’s a person out there and not some animal. In most cases the observer cannot just fire off a few shots to make sure, since that would give away his position. So most troops just wait until the suspected hostile gets close enough for confirmation (and some well-placed bullets) or moves away and is forgotten.

 

While U.S. troops have long enjoyed an edge at night because they had night vision equipment, increasingly the enemy is getting this stuff as well. While troops can negate the use of the older light enhancement (it intensifies available moon or starlight) night vision, the newer thermal (heat sensing) imaging night vision is more difficult to evade. The light enhancement devices can be avoided by assuming you cannot hide in the darkness and must simply stay out of sight as you approach, or try to move past, the enemy.

 

Since thermal imaging detects differences in heat and creates images of the warmer objects, a user of thermal imaging devices will be able to detect the outline of a person, or a vehicle (especially the engine and exhaust). But these images are not easy to confirm until they get fairly close. Thus troops equipped with a typical wearable thermal imager (like the U.S. ENVG) have a 50 percent probability of confirming the presence of individuals, even those hidden in the bush, at about 300 meters and an 80 percent probability at 150 meters. Troops wearing a Nemesis suit would have to be a lot closer before a thermal imager user could be sure. That means someone wearing a Nemesis suit could move a lot closer to users with thermal imaging gear and pass by undetected.

 

Electronic Weapons: Thermals Baffled By The Nemesis

The downside of the Nemesis is that the enemy could get suits like this, or access to the technology that makes Nemesis effective. Currently the Nemesis suits cost $2,900 each, which is another impediment to widespread use.

Service camouflage Uniforme - source GAO Sept 2012

Service camouflage Uniforme - source GAO Sept 2012

Aujourd'hui, l'armée américaine compte 10 types différents de camouflages, à motifs pixellisés ou à "rayures de tigre", à dominante verte, brune, voire bleue. Pour le Pentagone, cette source de multiplication des dépenses est inopportune en période de disette budgétaire.

 

21.11.2013 Le Monde.fr (AFP)

 

Conçus pour se fondre dans l'environnement, les camouflages d'uniforme sont devenus un moyen pour chaque service de l'armée américaine de se distinguer des autres, une coquetterie jugée bien coûteuse par le Congrès qui veut mettre fin à la gabegie.

 

Avant 2001, la situation était simple : tout le monde avait le même camouflage, à dominante verte pour les pays tempérés, couleur sable pour les zones désertiques. Mais à la faveur d'un budget en constante augmentation, marins, soldats, aviateurs et marines en ont profité pour afficher leurs particularisme au moment où le pays s'engageait dans deux conflits, en Afghanistan et en Irak. Aujourd'hui, l'armée américaine compte 10 types différents de camouflage, à motifs pixellisés ou à "rayures de tigre", à dominante verte, brune, voire bleue.

 

CAMOUFLAGE PIXELLISÉ

 

"Cela fait partie de l'esprit de corps. Après le 11-Septembre, les gens ont même commencé à porter leur uniforme camouflé au Pentagone", explique Larry Korb, du Center for American Progress. Un moyen pour ces militaires employés dans des bureaux de montrer qu'ils étaient eux aussi "sur le pied de guerre". Les marines, corps d'élite prompt à faire valoir sa différence, a été le premier à se distinguer dès 2002 avec un nouveau camouflage décliné en deux tons.

 

Hors des zones de combat, ordre est donné début novembre aux marines dans le monde entier de passer à la collection automne-hiver et de porter la version "terrain boisé" à dominante vert-brun. Début mars, la version sable fait son retour dans les rangs. Propriétaire de la licence, le corps interdit même aux autres services d'utiliser son uniforme et fait imprimer son logo lors de la fabrication du tissu pour s'en assurer. Au grand dam du Sénat, qui dans son projet de loi de financement de la défense pour 2014, actuellement en discussions, a inclus un amendement prévoyant "qu'aucun service n'interdit à un autre service d'utiliser un camouflage d'uniforme".

 

Le camouflage pixellisé de l'armée de terre, introduit en 2005, devait lui servir aussi bien dans les zones tempérées que désertiques. Mais il est vite apparu qu'il ne camouflait pas suffisamment, conduisant l'US Army à aller chercher en 2010 auprès d'une société privée un nouveau camouflage pour équiper ses soldats déployés en Afghanistan.

 

"DÉPASSEMENTS DE COÛTS"

 

Le reste de l'US Army, toujours équipé du camouflage pixellisé à dominante vert pâle et sable, a engagé des recherches pour trouver un nouveau camouflage. Le remplacement de l'uniforme actuel pourrait coûter 4 milliards de dollars sur cinq ans, pronostique un rapport du Government Accountability Office (le GAO), la cour des comptes américaine.

 

L'Air Force s'est elle aussi lancée en 2002 dans la recherche d'un nouveau type de camouflage pour aboutir cinq ans et 3,1 millions de dollars plus tard à un dessin dit à "rayures de tigre" aujourd'hui jugé totalement inefficace.

 

Quant à l'US Navy, c'est par un camouflage de bleu et de gris qu'elle s'est distinguée. L'habit n'est pas jugé assez résistant au feu, mais les mauvaises langues ironisent surtout sur le fait que le meilleur camouflage est celui qu'il apporte à un homme tombé à la mer...

 

Pour le Pentagone, cette source de multiplication des dépenses est inopportune en période de disette budgétaire. "Cela n'a rien à voir avec les dépassements de coûts du F-35 – qui se chiffrent en dizaines de milliards de dollars –, mais c'est quelque chose que toute personne normale considérerait comme de l'argent gaspillé", concède Larry Korb. Sénateurs comme élus de la Chambre des représentants veulent donc y mettre un terme.

 

Le projet de loi de financement présenté à la Chambre prévoit le retour à un uniforme commun le 1er octobre 2018. "Nous ne pouvons nous permettre d'avoir différents motifs de camouflage simplement pour marquer l'esprit de corps" de chaque service, dénonce l'élu démocrate William Enyart à l'origine de cet amendement. Le patron des marines, le général James Amos, a de son côté d'ores et déjà tonné devant les troupes qu'il n'avait "aucune intention de changer d'uniforme" et qu'il s'y accrocherait "comme un clochard à son sandwich".

Saab Multispectral Camouflage Nets For Canada

12/09/2013 by Paul Fiddian - Armed Forces International's Lead Reporter

 

Canada's Department of National Defence has placed an £8.2 million order for Saab Barracuda's MCS (Multispectral Camouflage System) nets.

 

Details of this contract emerged at the DSEI (Defence Security and Equipment International) event in London, which opened on 10 September and runs until tomorrow. Further options give the Department of National Defence the chance to order more nets, if required, between now and 2018.

 

The Saab Multispectral Camouflage System is designed to protect military vehicles on the move against optical and infrared target acquisition systems. It blends actual camouflage material with thermal protection, radar protection and near-infrared protection technologies.

 

Multispectral Camouflage System

 

Armoured vehicles tend to have a sizable cross section which, especially when operating in hot conditions, makes them more visible to enemy forces. Saab's Multispectral Camouflage System counters this effect by incorporating a non-glossy surface into its netting. As a result, vehicles wearing it are much harder to pick out.

 

‘Colours, near-infrared values and patterns can be adapted to the environmental conditions of the intended region', Saab explains. 'Conspicuous parts of the vehicle can be furnished with additional contour disrupters.'

 

Saab Camouflage

 

Saab Barracuda LLC is based in North Carolina and specialises in manufacturing and supplying low-observability military products, headed by its ULCANS (Ultra Lightweight Camouflage Net System).

 

Some 50 nations have now been supplied with Saab camouflage products. Combined, these systems serve to protect vehicles, camps and armed forces personnel against enemy sensors and target acquisition technologies.

 

"Saab has an unrivalled leading position in the world within Signature Management technology", said Saab Barracuda's Managing Director, Anders Wiman. "We continue to attract and retain new and existing customers around the globe."

 

The Canadian Department of National Defence was established in 1923, so celebrates its 90th anniversary this year. The Canadian's Government's highest-staffed department, equipped with the largest budget, it is tasked with defending the nation, both nationally and internationally.

Treillis camouflés: le Sénat et la Chambre US veulent un unique type

15.06.2013 par P. CHAPLEAU Lignes de Défense
 

Voilà qui pourrait bien mettre un terme aux projets de l'US Army de se doter d'un nouveau camouflage.

 

Cette semaine, les sénateurs puis les élus de la Chambre ont voté des propositions qui suggèrent que les forces armées américaines pourraient bien d'ici à octobre 2018 être dotées du même treillis, avec  le même camouflage. Finis le multicam des uns, les pixels des autres, le "blueberries" des marins: un seul dessin pour tous, avec des variantes dans les tons (désert, urbain etc).

 

Un peu de cohérence et des économies, voilà résumés les motifs des élus. Face à eux, deux écoles: les militaires qui admettent ces motifs et ceux qui, comme le Sergent Major Micheal Barrett, le sous-officier le plus haut gradé du corps des Marines, estiment que "l'uniforme donne des avantages spécifiques d'ordre tactique et psychologique". Barret s'est même fendu d'un communiqué pour défendre la spécificité du treillis des Marines: "Il fait partie de l'identité du Corps".

 

C'est pas gagné...

 

A lire ici une présentation des 29 types de camouflage utilisés dans les forces US.

Army Brown

June 4, 2013 by Think Defence

 

Did we discuss this, not sure?

 

From Akzo Nobel

The Ministry of Defence (MoD) asked AkzoNobel – makers of paints and coatings such as Intergard, Sikkens and Dulux – to develop a high-tech paint with a colour that would be suitable for the desert environments where most military operations are focused.

The new camouflage paint – known as Army Brown – will replace the sand colour that has been used on Army vehicles since before the Second World War.

To produce the new colour the MoD collected high resolution imagery in Afghanistan and flew rock and soil samples back  to Britain, where  a team at the Government’s Defence Science and Technology Laboratory developed a colour optimised for vehicles operating in that environment.

AkzoNobel scientists were then asked to develop a new water-based camouflage coating that conformed with the colour requirements. Developed under the Intergard brand the new Army Brown paint is similar to the tan colour used by the military in the US and Australia. It is designed to provide a better balance between arid, desert-like areas and the green zone with its lush vegetation.

AkzoNobel has developed a special temporary peelable coating which can be quickly sprayed or brushed onto the Army vehicles to provide a quick camouflage change and then peeled off. The revolutionary coating is capable of absorbing chemical warfare agents and stopping them getting through to the vehicle underneath. The contaminated coating can then be stripped off and disposed off. It also protects the vehicles against weathering and corrosion.

AkzoNobel scientists are currently working on further developments which would mean the coating would change colour when it absorbed toxic chemicals, alerting the soldiers that they are under chemical attack. Rather than just absorbing the chemicals it would also be able to neutralise them.

Army Brown is being used on the UK’s Foxhound light patrol vehicles. Army Brown has also been applied to some of the Warrior tracked armoured vehicles deployed to Afghanistan.

The Intergard coating has been developed by AkzoNobel’s aerospace coatings team. AkzoNobel’s Global Market Director Andrew Richardson said:

““We were delighted to be asked to work on the new colour for British Army vehicles and continue our partnership with the Ministry of Defence.
“The new paint colour has been specifically designed for the desert-like environment where most operations currently take place.
“The water-based paint will provide an exceptional performance in the most challenging environments.”

  • Even the paint is going hi tech, interesting about the peelable nature of it and the level of protection against chemical agents.
