moi je me souviens d'un reportage tv (française) sur l'entraînement  des légios en guyane , les gars qui sortait de st cyr venait ici préparer leur prochaine affectation en autre, et dans cette (école commando) y viennent aussi des brésiliens etc en fait beaucoup soldat de pays amis , et son venu les américains qui en quelque jour on plié leur valises ...réponse du sergent légionnaire  au journaliste qui lui demander pourquoi les ricains ne sont pas resté : ce devait être trop dur pour eux....

le probléme avec les américain ,c'est qu'ils ont un matériel au top  le matos du dernier cri  des crédits a n'en plus finir , il ne leur manque qu'une seule choses : les couilles .

Un document complet sur les commandos de marine US Créés en 1962 par le président Kennedy, les " Seals " sont les commandos de la marine US et leur milieu d'intervention premier est l'aquatique.

Mais ces petits groupes super entraînés peuvent également intervenir dans les airs et sur terre, en fait sur tout terrain en milieu hostile. Ils disposent d'un équipement hi-tech et subissent une sélection impitoyable et un entraînement rigoureux.

Leurs missions sont très variées : Préparation de débarquements- infiltration en territoire ennemi- destruction de matériel ennemi- enlèvements... mais aussi libérations d'otages. Ces missions les ont conduits sur des théâtres d'opération très variés, du Vietnam à l'Amérique centrale ou plus récemment en Irak.

Le fusil couteau suisse ?

Encore une idée genial sur le papier qui s'est avéré completement foireuse sur le terrain, un truc qui fait tout, mais mal, coute cher, pas fiable et fragile, en plus balade toi avec tout ce qui faut pour avoir les configurations differentes.

Demandez vous pourquoi ça a été abandonné.

AHLGREN, Va. � The unmanned military capabilities of a hybrid hovercraft and ground-effect vehicle are currently being investigated by a team of NSWC Dahlgren engineers and scientists in a ground effect research and development program known as Sly Fox Program Mission 9.

"The goal of Sly Fox Program Mission 9 is to integrate, test and evaluate the hybrid 19XRW vehicle�s utility as a military vehicle, including an unmanned capability," said Dohn Burnett, Sly Fox Program Manager. "This vehicle has great potential to provide very flexible warfighting capability across a broad spectrum of missions. This team of junior engineers and scientists will be exploring the concepts and designs for changing this vehicle from a commercial water craft to a military system."

Potential Navy and Marine Corps applications of the hybrid vehicle were presented to over 30 NSWC Dahlgren personnel before they watched the craft demonstrated in ground-effect mode over the Potomac River Test Range on July 25, 2007.

"A number of potential sponsor organizations have expressed interest in the hybrid craft�s unique characteristics," said Jim Hebert, NSWC Dahlgren lead for development of a militarized version of the vehicle. "Marine Corps Special Forces think it could potentially transport troops directly from ship to objective; members of the Surface Warfare Development Group believe it could address fast attack craft threats; and the Counter Narcotics Terrorism Group expressed interest in its possible use to locate and stop go-fast boats."

UH-19XRW Hovercraft Plans to transform the UH-19XRW into an unmanned craft integrated with weapons and sensors were also discussed at a similar event held at Quantico Marine Corps base on July 24. The Sly Fox team, comprised of junior engineers from Dahlgren and Quantico, are collaborating in all phases of design, development and evaluation.

Although designed as a normal hovercraft, surfaces can be added to the craft for operation in ground-effect. In this mode, the craft can reach a height of six feet above the surface, enabling it to operate where many conventional boats cannot. It can achieve a faster speed than fast boats while going over obstacles such as sandbars, marshes, land, and rocks.

"The UH-19XRW is a ground effect machine with an attitude. Making this craft unmanned opens the door to a wide variety of operations," said Greg Buchanan, Sly Fox mentor. "I�m excited to see what innovative designs the team comes up with."

The Sly Fox team envisions a militarized craft - operated in a manned or unmanned variant � that can be deployed for littoral combat, amphibious operations, riverine and coastal combat. "Unlike a normal hovercraft which is limited to fairly smooth terrain, this craft can operate over rugged terrain � and fast," added Buchanan. "We�ve discussed the craft�s potential around littoral environments but the field is wide open from desert operations to potential missions in the artic. The team�s testing will also include operations over fields of grass."

The purpose of the briefings at Dahlgren and Quantico was to raise awareness of the craft�s potential impact on several important missions. NSWC Dahlgren is also looking for sponsors to support an advanced development program to develop the mission specific modules and weapons.

Je colle ici un peu au hasard les infos sur le stilleto.

http://blog.wired.com/defense/2008/09/stiletto-vs-dru.html

... In the early days of August, a suspected drug-running boat zoomed through the Straits of Florida, trying to outrun her American pursuers. The drug boat zigged and zagged near reefs and sandbars at 42 knots, and skimmed over water as little as five feet deep. Ordinarily, that would have been enough shake off any Coast Guard cutter or Navy frigate chasing her -- those vessels can't be in such shallow water. But this pursuer kept coming, and coming. Finally, after two hours, the drug boat ran out of gas. During their interrogations, the drug-running suspects said it was like being chased by a UFO.

The ship wasn't alien, however. It was an 80-foot, 60-ton, $6 million experimental vessel, built for the Defense Department, called the Stiletto. A Batman-esque, double-M-shaped hull allows Stiletto to operate in extremely shallow waters. A carbon fiber body let's the thing cruise at up to 60 knots. And a series of gigbit ethernet connections allows radars to drone-controllers to infrared sensors to be positioned anywhere throughout the ship. ...

High-Tech 'Bat-Ship' Still Needs Work: Report

StilettoThe military is pretty psyched about their new, ultra-fast, high-tech, Batman-esque ship that scared off drug dealers in Colombia -- and chased down suspected drug runners in the Florida Straits. But there are atill some problems with  80-foot, 60-ton, $6 million experimental "Stiletto," a Pentagon report reveals.

The Stiletto's 35-foot Rigid-Hull Inflatable Boat was too heavy, and too unreliable, according to the report, obtained by Information Dissimenation. Heavy seas keep the ship from going too fast. And the ship's communications and intelligences systems need work, too. Stiletto not only can't access the Secret Internet Protocol Router Network -- the military's classified version of the Internet. The ship's maritime radar isn't "capable of accurately identifying illicit trafficking vessels."

Still, the tone of the report is triumphant. Stiletto's mission for U.S. Southern Command, to Colombia and back, "stands out as an excellent case study for how an innovative effort can be conceived, organized, planned, and executed within a very short period of time." The word around the Pentagon is that the bat-ship may be headed back down south again soon.

Le rapport détaillé http://informationdissemination.blogspot.com/2008/10/observing-m-80-stiletto-opeval.html

...

Finally, some platform observations:

    * The crew covered 6,000 nm while underway on Stiletto.

    * When the seas were calm, Stiletto could transit very quickly; they were able to “get somewhere very fast.”

    * The range of operations was shorter than expected because Stiletto’s top speed was less than they originally anticipated. A mission typically requires eight hours. However onboard Stiletto in this deployment, it “took two hours to transit out and two hours to RTB, leaving four hours to patrol.” Crew members suggested that four hours to patrol is not enough time on-station to have success.

    * Most of the deployment time was spent patrolling with Stiletto 12 miles offshore in an area with 4 ft seas, which reduced Stiletto’s speed advantage.

    * Stiletto became a “responsive” asset, due in part to lack of secure data which limited mission planning at sea.

    * The Stiletto team reported that they had “RHIB launch/recovery down to a science.” The crew reported that RHIB recoveries always present risk, and they were able to successfully launch and recover the RHIB.

    * The team conducted the RHIB launching in 6-8 ft seas, and another in occasional 8-ft seas. They reported that while it is typically too risky to conduct RHIB launch / recoveries in sea states this high, it could be done onboard Stiletto in “life or death” situations.

    * There was one particular mission where the Stiletto had a go-fast target; Stiletto was in port and launched. After transiting out and seeing the rough sea state, the Chief made a decision that the water was too rough and to turn back – a decision that the LEDET team supported. At the same time, other COL support and military vessels, including a Midnight Express, turned back as well.

    * In regards to the Florida Straits mission: USCG Sector Key West (KW) “got Stiletto for two days to conduct patrols.” During that time, the Army mariners work with four USCG groups, two from D7 TACLET and two from Sector KW. On the second day, another two came from the USCG operations center. In the morning of Day One Stiletto participated in a demo with the evaluation team and other DVs, and in the afternoon it patrolled the area. The morning served as integration training for the mariner crew and USCG members. On Day 2 Stiletto went northwest toward Williams Island, capitalizing on its shallow draft capability; during that time, Stiletto used D7 for law enforcement, not Sector KW. Stiletto was approximately five miles offshore Andros Island when the crew visually spotted a target; they then found it on FLIR (never saw the target using the radar). They chased this vessel in the shallow waters for approximately 15-20 minutes. When the suspect could not lose Stiletto, he then turned north toward Marathon in the open waters. However the waters proved to be too rough for the go-fast. The sea state was approximately 2-3 feet, and Stiletto was moving at 42.4 kts. At this rate and in these conditions, Stiletto was able to apprehend go-fast within two hours. Also involved in the apprehension was Customs and Border Patrol (CBP) aircraft; the aircraft had been flying overhead when it saw the Stiletto chase. After contacting Stiletto and learned it was not training they were watching, CBP assisted with the interdiction. Additional assistance came from Sector KW, OPVAC (USARSO Counter-Drug program) and three USGC members. There was also another go-fast on scene that other USCG officials apprehended. Once concluded, DEA officials said that the individuals apprehended were actually TOIs that had been identified earlier.

Finally we conclude with this.

    * Several reasons for the lack of interdiction and counter-drug activities in the Colombian area were given by interviewees. Some suggested that Colombian police and Navy vessels were in the region at the same time, either warding away potential suspects or apprehending them without Stiletto’s assistance. Others suggested that people in Colombia knew Stiletto was in the area because of information leaks. As an example, the crew stated that one could “Google Stiletto and find updated data, pictures etc. The Saturday evening before Stiletto deployed [we] painted the roof a white color; by that Monday, pictures of Stiletto with a white roof were on the internet.” When the crew researched Stiletto, they found deployment dates and port stops listed online. Additionally others suggested that the lack of interdictions may be due to the stealth-like appearance of Stiletto because it attracts a lot of attention. “It was impossible for Cartagena citizens to not know about Stiletto. To pull into port there, you have to pull by all the high rises. We deployed at all hours, day and night; it was too cool looking for people not to know we were there.”

Welcome to 4GW at sea. This last part was one aspect I nearly didn't post, except to add context to the discussion. This is a good example why these platforms would be better suited for operations from a sea base. Stiletto is a stealth ship, but by the testimony of the ships own crew the stealth advantage was impaired in part by the MK 0 eyeball, the bane of stealth for any surface ship at sea.

The Department of Defense's high-speed experimental boat Stiletto will depart from Key West, Fla., June 13 to the Caribbean where it will support U.S. and multinational counter-illicit trafficking (CIT) operations and conduct operational testing.

The 88-foot long, 60-ton Stiletto will deploy to the Caribbean basin through the summer under the operational control of U.S. Naval Forces Southern Command (USNAVSO) and U.S. 4th Fleet and tactical control of Joint Interagency Task Force-South (JIATF-S). Stiletto is manned by a joint U.S. Army and U.S. Navy crew and includes an embarked U.S. Coast Guard Law Enforcement Detachment.

"A unique aspect of the region, with its proximity to the United States, is our ability to support the testing and evaluation of select new and developing programs and concepts," said Rear Adm. Joseph D. Kernan, commander, NAVSO and U.S. 4th Fleet. "Stiletto is a great example of employing innovative technologies while also executing an important mission. It is manned by a joint and interagency crew, and we work with some of our partners in the Caribbean to counter-illicit trafficking."

Stiletto's innovative hull construction and M-shaped design make it lightweight and easy to maintain, allowing Stiletto to reach speeds of up to 50 knots under calm sea conditions and operate in shallow waters. It is also equipped with state-of-the-art navigation, communications and network interface capabilities, allowing its crew to support a wide range of missions, ranging from mine clearing operations to the rapid delivery of humanitarian aid following natural disasters.

This is Stiletto's second deployment to the USSOUTHCOM's area of focus and the second deployment in direct support of U.S. and international CIT operations.

Stiletto was designed and built under a contract by the Pentagon's Office of Force Transformation (OFT). OFT accepted delivery of Stiletto in May 2006, and Stiletto has undergone testing by the Department of Defense for its usefulness in littoral operations and interoperable environments.

USNAVSO is the U.S. Southern Command (USSOUTHCOM) naval component command. U.S. 4th Fleet is the numbered fleet assigned to USNAVSO.

JIATF-S is the USSOUTHCOM component that oversees U.S. military support to regional CIT operations.

Bonjour savez vous pourquoi les Seals utilisent à présent des M4 en version courte, dans les 10" je crois le longueur du canon.

Plusieurs photos en Afghanistan montrent les opérateurs ainsi équipes. je croyais que la tendance pour ce pays était des armes qui portent plus loin.
