71-600: Orange William was a British project to develop a long-range anti-tank missile as a possible alternative to the Malkara being developed in Australia . The project was drawn up in 1954 and the resulting contract won by Fairey Engineering in 1956. It was very similar to Malkara in form and layout, including the Malkara's distinctive square fuselage. It differed primarily in its guidance system ( semi-automatic command to line of sight ) and

The USAF uses Air Force Specialty Code (AFSC 3E9X1) U.S. Air Force Emergency Management , who are also CBRN Specialists. The USAF trains all US Airmen pursuing a career in counter-CBRN operations at the USAF CBRN School at Fort Leonard Wood. The USMC uses CBRN as an abbreviation for two military occupational specialties . The Marine Corps runs

355-426: A front-line weapon. The second factor is that as the development of the new main battle tank and its gun proceeded it became clear that it would be able to deal with any tank which, so far as we can see ahead, it is likely to have to meet. Purchases of Malkara proceeded as it was small and light enough to be transported by air, in contrast to anti-tank guns , the previous long-range weapon. It entered service in 1958 on

426-406: A joystick or similar control system to steer the missile to a target. One disadvantage of this is that an operator must keep the sight's reticle cross hairs on a target and then steer the missile into the cross hairs, i.e., the line-of-sight. To do this, an operator must be well trained (spending many hours on a simulator) and must remain stationary and in view of a target during the flight time of

497-466: A laser, electro-optical imager ( IIR ) seeker or a W band radar seeker in the nose of the missile. Once the target is identified, the missile needs no further guidance during flight; it is " fire-and-forget ", and the missile operator is free to retreat. However, fire-and-forget missiles are more subject to electronic countermeasures than MCLOS and SACLOS missiles. Examples include the German PARS 3 LR and

568-425: A limited ability to penetrate modern armour, and other issues. Still, many countries maintain significant stockpiles. Approximately, first generation ATGMs have an effective range of 1500m and the ability to penetrate 500mm of rolled homogeneous armor . Second-generation semi-automatically command guided to line-of-sight, or semi-automatic command to line of sight (SACLOS) missiles require an operator to only keep

There is a risk that global warming in the Arctic can thaw the permafrost, leading to new infections in reindeer. An anthrax outbreak in 2016 in reindeer caused the Russian Armed Forces to evacuate a nomadic reindeer herding tribe. In May 2012, BioPrepWatch reported that

710-445: A part of a re-design is possible, as in the numerous types derived from the T-72 . Slat armor is lighter and as such can be added to many vehicles after construction but still adds both bulk and weight. Particularly for vehicles that are designed to be transported by cargo aircraft, slat armor has to be fitted in the field after deployment. Either approach can never offer complete coverage over

852-458: A vehicle from any angle of attack. While these may be answered and allow for lightweight, highly maneuverable vehicles that are strongly defended against missiles and rockets that are extremely well suited for urban and guerrilla warfare, such a system is unlikely to be as effective against kinetic energy projectiles, making it a poor choice for fighting against tanks. As kinetic energy projectiles move faster than guided missiles, this often means that

923-559: A wire-guided anti tank missile derived from the Ruhrstahl X-4 air to air missile concept in the closing years of World War II. Known as the X-7, it was probably never used in combat and allegedly had serious guidance to target issues. It never entered service, though a few were produced. First-generation ATGMs use a type of command guidance termed manual command to line of sight (MCLOS). This requires continuous input from an operator using

994-458: Is a class of protective measures taken in situations where chemical , biological , radiological , or nuclear (including terrorism ) hazards may be present. CBRN defense consists of CBRN passive protection, contamination avoidance, and weapons of mass destruction mitigation. A CBRN incident differs from a hazardous material incident in both scope (i.e., CBRN can be a mass casualty situation) and intent. CBRN incidents are responded to under

The Air Force is making special teams for transporting victims from CBRN attacks/accidents. The term CBRN is in common use in disaster and emergency services organizations across the country. Since July 2005,

1278-600: Is usually much weaker. Third generation systems and beyond are generally much more expensive than second generation systems. Fourth generation fire-and-forget anti tank guided missiles have larger range and rely on a combination of seeker for guidance. Examples include India's SANT , which has a stand-off range of 15 to 20 km (9 to 12 mi), uses dual seeker configuration of electro-optical thermal imager (EO/ IR ) and millimeter-wave active radar homing for control and guidance with lock-on before launch and lock-on after launch capabilities. Some ATGMs, notably

1349-779: The Canadian Armed Forces also started using the term CBRN Defence , instead of NBC Defence , due to the increased threat of dirty bomb use (which is radiological in nature). CBRNE is a new term that is being used in both civilian and military organizations. The Canadian Joint Incident Response Unit is a Canadian Forces unit, under the direction of the Canadian Special Operations Forces Command , charged with supporting "the Government of Canada in order to prevent, control and mitigate CBRN threats to Canada, Canadians and Canadian interests." All members of

1420-498: The Canadian Armed Forces are trained in CBRNE defense and maintain minimum standards, tested at least every three years. At the provincial level, cities are provided opportunities for emergency services with CBRN training. In Ontario, emergency services in Windsor, Peterborough, Toronto, and Ottawa have obtained CBRN standing at NFPA Standard 472 Level 3 Technician level. In mid-July 2016,

1491-575: The Chieftain tank which was considered able to deal with any Soviet tank available. Malkara was purchased for its original intended use to give airborne infantry forces the ability to deal with heavy tanks. As a new heavy anti-tank missile was still desirable, new projects started as the Quickfire and Swingfire weapons. The latter would go on to be the British Army 's primary heavy anti-tank weapon into

1775-623: The Humber Hornet . Fairey was handed the production contract for Malkara in the UK as well as sales efforts in Europe, although no further sales were won. The British Army remained interested in a long-range heavyweight missile, and started the Quickfire and Swingfire projects soon after, the later of which entered service in 1966. Anti-tank guided missile Earlier man-portable anti-tank weapons , like anti-tank rifles and magnetic anti-tank mines , generally had very short range, sometimes on

1846-818: The Israel Defense Forces to defeat the Saggers involved firing in front of the tank to create dust. While fire-and-forget missiles have definitive advantages in terms of guidance and operator safety, and include abilities such as top attack mode, older missiles continue in use, both in the front line armies of less developed countries, and in reserve service the world over, due to their lower cost or existing stockpiles of less advanced weapons.

As was noted by Christopher Soames in parliamentary debate on 9 March 1960: There were two reasons which led us to cancel Orange William. The first is that, as its development proceeded, it became clear that if it was to meet the Staff requirement it would have to be of such an order of complexity as to make it unsuitable as

2130-457: The 1990s. Malkara, the British Army 's first anti-tank missile, was developed in partnership with the Australian Army . Malkara was a heavy vehicle-borne, long-range weapon, which used an optical system on the launcher vehicle for tracking.

The Irish Army runs CBRNE defense courses has detection equipment, and decontamination equipment and is reported to have purchased 10,000 protective CBRN/NBC suits , enough for all of its personnel. All Army Reserve personnel undergo CBRN warfare defense training. The Irish national police force, the Garda Síochána , has a number of nationwide CBRN response teams. The teams are based regionally (in six regions; Dublin, Eastern, Northern, Southern, South-Eastern & Western) and began operating in 2004 with 100 trained officers (170 responders trained throughout

3266-803: The country as of 2009). There is a requirement for members to be re-certified within 18 months of training. CBRN response teams are trained by the Garda Tactical Training Unit, and supported nationally by the Emergency Response Unit (ERU). Other emergency services also have limited CBRN expertise, such as the Health Service Executive (HSE) and Dublin Fire Brigade (DFB), which have a Hazardous Materials (Haz-Mat) and Chemical Incident Unit. 14 CBRN Regiment (Chemical Biological Radiology and Nuclear Regiment), Sri Lanka Engineers

3337-402: The distance between them carefully measured. One operator manually tracked the missile with a small spotting system, while a second did the same for the target. As the missile was travelling along the hypotenuse of the triangle formed by the launcher, guidance vehicle and target, the guidance had to be managed by a computer. The computer calculated corrections and sent commands to the missile via

3408-424: The electronics kept it at a constant altitude. The system proved to be difficult to use in practice; operators would guide the missile until they saw it overlapping the target, by which time it was often travelling rapidly in the sideways direction and had to be stopped by inputting the opposite direction. This caused the missile to fly back and forth across the target path and was especially difficult to get right if

It used a 26 kilograms (57 lb) high-explosive squash head (HESH) warhead. Other early first generation ATGMs include the West German Cobra and the Soviet 9M14 Malyutka . In 2012, first-generation systems were described as obsolete due to low hit probability,

3692-406: The launcher to remain completely under cover while the guidance vehicle could be heavily camouflaged and guide the missiles from a forward location. Although the range of the missile was 6,000 yd, the engagement range was 4,000 yd, the idea being that the launcher could be up to 2,000 yd behind the guidance vehicle. In order for the system to work, the two vehicles had to be set up and

3763-531: The missile itself was almost identical at first glance, Orange William was somewhat longer with slightly smaller mid-set wings, and had a larger motor that provided up to 6,000 yards (5,500 m) range. The rear mounted controls were powered by a 3000 psi compressed air bottle, and the electronics by a molten salt battery . To protect the launcher from attack, in Orange William the launcher and guidance system were placed on two different vehicles. This allowed

3834-463: The missile. Because of this, the operator is vulnerable while guiding the missile. In addition to the low kill probability, other problems with first generation ATGMs include slow missile speed, high minimum effective range, and an inability to use top attack missiles. The first system to become operational and to see combat was the French Nord SS.10 during the early 1950s. It entered service in

3905-410: The much larger return from the jammer, with the operator unlikely noticing the difference without a radar screen to see the return. However, any missile that has a backup tracking system can defeat jamming. Active protection systems show a great deal of promise, both in counteracting ATGMs and unguided weapons. Compared to armor systems, they are very lightweight, can be fitted to almost any vehicle with

3976-548: The order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave light infantry real capability on

Army All personnel are trained in CBRN through basic training and are to complete an online assessment annually. The British Army has a single dedicated regiment for all C-CBRN (Counter) matters in the armed forces. 28 Engineer Regiment is the only regiment within the armed forces that has full C-CBRN capability. Formed in 2019

4118-448: The regiment will officially be at full operational capability from early 2023, with the need for CBRN specialists becoming of more importance. Personnel within the regiment are trained in live environments where CBRN materials are used. The United States Army uses CBRN as an abbreviation for their Chemical, Biological, Radiological, and Nuclear Operations Specialists ( MOS ). The United States Army trains all US Army soldiers pursuing

4189-479: The sensors attached to an active protection system can not keep up. Traditionally, before "fire-and-forget" ATGMs were used, the most effective countermeasure was to open fire at the location where the missile was fired from, to either kill the operator or force them to take cover, thus sending the missile off course. Smoke screens can also be deployed from an MBT's smoke discharger , and used to obscure an ATGM operator's line of sight. Other improvised methods used by

4260-416: The shaped charge that makes the warhead effective. Both come with the downside of significant weight and bulk. Reactive armor works best when a vehicle is specifically designed with the system integrated and while developments continue to make armor lighter, any vehicle that includes such a system necessitates a powerful engine and often will still be relatively slow. Inclusion of such armor in older vehicles as

Automatic guidance commands are sent to the missile through wires or radio , or the missile relies on laser marking or a TV camera view from the nose of the missile. Examples are the Russian 9M133 Kornet , Israeli LAHAT , the NLOS version of Spike , and the American Hellfire I missiles. The operator must remain stationary during the missile's flight.

4473-449: The target was moving. Another concern was that in order to launch, the missiles had to be raised into the air where they became visible to the enemy and invited counterattack. The design included features to reduce this time as much as possible, but the smoke left after firing indicated its rough location long enough to give it away. Orange William was essentially a version of Malkara that attempted to address these two shortcomings. Although

The initial contract called for testing in 1960 with a 1962 in-service date. Problems with the command link proved difficult to solve and later appeared to require outright replacement. The project was cancelled in September 1959 as it would not enter service before

4615-423: The vehicle, leaving tracks or wheels particularly vulnerable to attack. Jamming is potentially an effective countermeasure to specific missiles that are radar guided, however, as a general purpose defense, it is of no use against unguided anti-tank weapons, and as such it is almost never the only defense. If jamming is used continually, it can be extremely difficult for a missile to acquire the target, locking on to

4686-605: Was believed that the extreme rearward location of the launcher vehicle meant it did not have to be armoured. The original vehicle selected for the role was the 5-ton FV420 tracked carrier. This proved too fragile for the field and a new vehicle based on the FV421 tracked carrier replaced it, creating the FV426. This was armoured with 12 mm (0.47 in) steel plate to withstand 0.5 in (12.7 mm) heavy machine gun fire and artillery bursts within 20 ft (6 m) and added nuclear and chemical weapon defences . Two prototypes were scheduled for delivery in May 1960. In testing, it

A 25 GHz radio link was proposed to replace the IR system, but never proceeded with as the project "ran into the sand." The complexity of the system and the ongoing problems with the command link led to its September 1959 cancellation after spending an estimated £5,000,000. By this time,
