American production of the weapon began by Hesse- Eastern in 1. Nammo Raufoss AS in Norway and their subsidiary Nammo Talley, Inc. Arizona.[5]In early 1. M7. 2 LAW was adopted by the U. S. Army and U. S.
Marine Corps as their primary individual infantry anti- tank weapon, replacing the M3. HEAT rifle grenade and the M2. A1 "Super Bazooka" in the U. S. Army. It was subsequently adopted by the U. S. Air Force to serve in an anti- emplacement/anti- armor role in Air Base Defense duties.[6][note 1]In the early 1. M7. 2 was slated to be replaced by the FGR- 1. Viper. However, this program was canceled by Congress and the M1.
AT4 was adopted instead. At that time, its nearest equivalents were the Swedish Pskott m/6.
Miniman) and the French SARPAC.[note 2]Background[edit]The increased importance of tanks and other armored vehicles in World War II caused a need for portable infantry weapons to deal with them. The first to be used (with limited success) were Molotov cocktails, flamethrowers, satchel charges, jury- rigged landmines, and specially designed magnetic hollow charges. All of these had to be used within a few meters of the target, which was difficult and dangerous. The U. S. Army introduced the bazooka, the first rocket- propelled grenade launcher. Despite early problems, it was a success and was copied by other countries. However, the bazooka had its drawbacks. Large and easily damaged, it required a well- trained two- man crew.
Germany developed a one- man alternative, the Panzerfaust, having single- shot launchers that were cheap and requiring no special training. As a result, they were regularly issued to Volkssturm home guard regiments.
They were very efficient against tanks during the last days of World War II. However, the Panzerfaust was not a rocket launcher but instead a recoilless rifle. The M7. 2 LAW is a combination of the two World War II weapons. The basic principle is a miniaturized bazooka, while its light weight and cheapness rival the Panzerfaust. Description[edit]. LAW prototype, showing the rejected front sight that also served as the front cover. The weapon consists of a rocket within a launcher consisting of two tubes, one inside the other.
While closed, the outer assembly serves as a watertight container for the rocket and the percussion- cap firing mechanism that activates the rocket. The outer tube contains the trigger, the arming handle, front and rear sights, and the rear cover. The inner tube contains the channel assembly, which houses the firing pin assembly, including the detent lever.
When extended, the inner tube telescopes outward toward the rear, guided by the channel assembly, which rides in an alignment slot in the outer tube's trigger housing assembly. This causes the detent lever to move under the trigger assembly in the outer tube, both locking the inner tube in the extended position and cocking the weapon. Once armed, the weapon is no longer watertight, even if the launcher is collapsed into its original configuration. When fired, the striker in the rear tube impacts a primer, which ignites a small amount of powder that "flashes" down a tube to the rear of the rocket and ignites the propellant in the rocket motor. The rocket motor burns completely before leaving the mouth of the launcher, producing gases around 1,4. F (7. 60 °C). The rocket propels the 6. As the warhead emerges from the launcher, six fins spring out from the base of the rocket tube, stabilizing the warhead's flight.[note 3] The early LAW warhead, developed from the M3.
HEAT rifle grenade warhead, uses a simple, but extremely safe and reliable, piezoelectric fuze system. On impact with the target, the front of the nose section is crushed causing a microsecond electric current to be generated, which detonates a booster charge located in the base of the warhead, which sets off the main warhead charge.
The force of the main charge forces the copper liner into a directional particle jet that, in relation to the size of the warhead, is capable of a massive amount of penetration. A unique mechanical set- back safety on the base of the detonator grounds the circuit until the missile has accelerated out of the tube. The acceleration causes the three disks in the safety mechanism to rotate 9. Ammunition[edit].

Improvements to the launcher and differences in the ammunition were differentiated by a single designation. The most common M7. A2 LAWs came prepacked with a rocket containing a 6.

A training variant of the M7. LAW, designated the M1. This weapon is reloadable and uses the 3. M7. 3 training rocket.
A subcaliber training device that uses a special tracer cartridge also exists for the M7. A training variant used by the Finnish armed forces fires 7. The US Army tested other 6. M5. 4 rocket motor used for the M7.
The M7. 4 TPA(Thickened Pyrophoric Agent) had an incendiary warhead filled with TEA (triethylaluminium); this was used in the M2. A1 FLASH (FLame Assault SHoulder weapon) 4- tube launcher.
The XM9. 6 RCR(Riot Control Rocket) had a CS gas- filled warhead for crowd control and was used with the XM1. Once fired in combat, the launcher is required to be destroyed to prevent its use by the enemy as a booby- trap; the enemy could collapse the launcher to its original configuration, fill it with explosives, and rig it to explode if moved by a soldier believing it to be unused. Due to the single- use nature of the weapon, it was issued as what is called a "wooden round"[8] of ammunition by the Canadian Army and the United States Army, requiring no checks or maintenance, just as small- arms ammunition can be stored in the same manner for years without any problems. Service history[edit]Australia[edit]The M7.
Australian service since the Vietnam War.[9][1. Currently, the Australian Defence Force uses the M7. A6 variant, known as the Light Direct Fire Support Weapon,[1.
The weapon is used by ordinary troops at the section (squad) level and complements the heavier 8. Carl Gustav recoilless rifle and Javelin missile, which are generally utilized by specialized fire support and anti- armor troops.[1.
Taiwan(The Republic of China Army) uses the M7. It is used primarily as a backup to the Javelin and M1. AT4) anti- tank weapons.[citation needed] The weapon is later reverse- engineered into the "Type 1 6.
Anti- tank Rocket" but is more- popularly nicknamed as the "Type 6. Packing crates are used to demonstrate the danger of the M7. Finland[edit]The M7. LAW is used in the Finnish Army (some 7. KES 7. 5 (M7. 2A2, no longer in service) and 6. KES 8. 8 (M7. 2A5).
In accordance with the weapon's known limitations, a pair of "tank- buster" troops crawl to a firing position some 5. LAWs, which are then used in rapid succession until the target is destroyed or incapacitated. Due to its low penetration capability, it is used mostly against light armored targets. The M7. 2 is the most common anti- tank weapon in the Finnish Army.[citation needed] Finland has recently upgraded its stocks to the M7. EC LAW Mk. I version. It is designated 6.
KES 1. 2.[1. 3] Claimed penetration for the M7. EC LAW is 4. 50mm of rolled homogeneous armor steel plate, nearly twice that of the M7. A2.[1. 4] It also fields the bunker- buster version, named M7. ASM RC, and locally designated 6.

Medieval Crossbow: 1. Steps (with Pictures)Templates: To speed things up I made templates from thin MDF, sometimes called flexi board. Watch Cabin Boy Streaming. It is very smooth and free of flaws, perfect for templates if you do not require more than 4 inches in width.
The PDF template files are uploaded here for everybody to enjoy they are drawn to make use of these sizes. Take a look at the shapes and if you don’t like the shapes modify them to suit. I cut the MDF on the laser cutter but the band saw and drum sander can be used also, if you really want to go medieval you can do it all with hand tools J, however you will be in the shop for a while… You can also cut the templates from some cardboard or whatever appropriate material is at hand…You can also free hand draw the design of your choice, you cannot go wrong, as crossbows were made in all kinds of sizes and shapes. Only the mechanism principles matter, the rest is just “stile”. Just try to stay symmetric. A search on the internet will reveal hundreds of designs.
Here are some guidelines: The handheld crossbows were held like long guns, so about 3. The Arrows (Bolts) were no longer than 1. The release cam (called a Nut) was no bigger than 1.
The bows were made from wood, wrought iron, or horn and sinew composite, for the ultimate in draw performance. The bow was laced to the Tiller with some various natural fibers or leather or in the case of wrought iron bows, with iron side plates wedges and pins. The bow string was made of some natural fiber twisted and wrapped to resist wear and tear and increase strenght. For finishing the wood surfaces, probably linseed oil, bees wax or similar stuff was used. Sometimes embellishments made from various materials were used for decorative purpose especially on hunting crossbows.
Position templates securely using the guide lines etched on them using the edges and center joint of the stock as registration marks and draw contour lines with a pencil. If you made templates from MDF the tiny holes provided are for some finishing nails used to secure the MDF in place. Look at the lines and See if you like the shapes resulting and modify them if they do not suit your build and stature.
