THERE IS A TECHNICAL SUPPORT PASSPHRASE SOMEWHERE IN THIS NOTECARD, WHICH YOU MUST USE WHEN FIRST CONTACTING YOUR TECHNICAL CONTACT ABOUT THIS PRODUCT. We just do this to make sure you've read the instructions so that we can assist people with truly vexing problems not already answered within.
Equipping The M136 AT4
From your inventory, right-click and 'wear' the M136 AT4. It will by default attach to your right hand. The animation for holding the AT4 depends on the weapon being in that hand. Upon attachment, the AT4 enforces a 15-second wait before arming.
Reload Timer: This timer counts down until the weapon is armed, and will also display "RDY" when ready, or "OCS?" if it has not yet received OCS verification for the player.
You must have your OCS HUD on for the weapon to fully arm.
Arming Indicator and Front Sight: These both change color to show the arming state of the weapon. Red indicates the weapon is disarmed, and checking the Reload Timer will show how long until it is rearmed. Yellow shows the weapon is armed but OCS verification has not been received. Green means it is armed and ready to fire.
Firing: The AT4 is fired from mouselook. While its trajectory is relatively flat, you will need to account for some arc in its flight. Left-click your mouse to fire. You will hear a click, then there will be a short delay as the fuse ignites the cartridge inside the launcher. Then you will hear a thump and the warhead will launch.
After firing, the weapon requires a five-minute wait for reloading. You may detach it, and it will be reloaded when you get it back from inventory after the 5 minutes are up.
The AT4 is very powerful and can often disable armored vehicles, and take them out in one shot if it hits in a weak spot. It will also damage all but the strongest buildings, and has a significant area effect against infantry. Keeping the area effect in mind, it is not wise to use the weapon at short ranges, or when the target is in close proximity to friendly forces.
Your support phrase is "Salt water counterbalance."
A Note About Animation Overriders (AOs)
Because of how Second Life handles animations, some AOs may interfere with the animations done by your OCS gear. AOs also frequently interfere with mouselook aiming, making a weapon appear to not shoot where one is aiming. It is suggested that you shut off any AOs while using OCS gear.
The End
In short, this recoilless rifle was created for the Omega Combat System primarily to give infantry a fighting chance against heavy armor. The Omega Concern promises to support your M136 AT4 for the lifetime of the product, with free upgrades for all of version 1.x, and lifetime bug fixes.
Above all else, have fun. :)
AT4From Wikipedia, the free encyclopedia The AT4 (or AT-4) is a portable one-shot anti-tank weapon built in Sweden by Saab Bofors Dynamics (previously Bofors Anti Armour Systems). In the U.S. and NATO inventory it replaces the M72 LAW (Light Anti-armor Weapon). Saab has had considerable sales success with the AT4, making it one of the most common light anti-tank weapons in the world. It is intended to give infantry units a means to destroy or disable armored vehicles and fortifications they may encounter (though it is not generally sufficient to defeat a modern main battle tank). The launcher and projectile are manufactured, pre-packed, and issued as a single unit of ammunition (rather than a weapon system), with the launcher discarded after use. Development The AT4 is a development of the 60 mm Pskott m/68 (Miniman), adopted by the Swedish army in 1960's. Like the m/68, the AT4 was designed by Förenade fabriksverken (FFV) and manufactured at their facility at Zakrisdal, Karlstad, Sweden. Even before the AT4 had been adopted by Sweden it participated in a competition for a new anti-tank weapon for the U.S. Army. Runners up were the AT4 and the German Armbrust. Though impressed with the AT4, the US Army saw room for improvement—specifically the sights and slings, which were redesigned. Thereafter, the AT4 was adopted by the U.S. Army as the M136 antitank grenade launcher (LAW). The Swedish army recognised these improvements and subsequently adopted the Americanized version of the AT4 as the Pansarskott m/86 (Pskott m/86). In the early 1990s there were tests with new 120 mm version with a tandem charge that would be able to penetrate the front armour of any modern main battle tank (MBT). However the project was canceled due to the dissolution of the Soviet Union and cuts in defense budget. Operation The AT4 operates on the principle of a "recoilless weapon," meaning that the forward inertia of the projectile is balanced by the mass of propellant gases ejecting out the rear of the barrel. Since the weapon generates almost no recoil, a relatively large projectile can be fired which would otherwise be impossible in a man-portable weapon. Additionally, since the barrel does not have to contend with the extreme pressures found in traditional guns, it can be designed to be very lightweight. The disadvantage of this design is that it creates a large "back-blast" area behind the weapon which can cause severe burns and pressure injuries—both to friendly personnel in the vicinity of the user and, in some cases, to the user himself. This makes it difficult to employ in confined areas. The problem of back-blast has been eliminated recently with the AT4-CS. The new weapon deploys salt-water from the rear when it is fired. This spray captures and dramatically slows down the pressure-wave. The improved weapon allows troops to fire at armoured personnel carriers or tanks without exposing their bodies to enemy fire. To fire, the user must first ensure that no friendly troops or equipment are present in the back blast area. If firing from the prone, (i.e. lying on his stomach) he must also place his legs well to the side to avoid burning himself. He then disengages two safeties, cocks a mechanical firing pin and presses a trigger button. Aiming is accomplished via range-adjustable plastic sights, which are concealed beneath sliding covers for transport. Alternatively, the weapon can carry an optical night-sight on a removable mount. The AT4 requires little training and is quite simple to utilize, making it suitable for general issue. Because the expensive unit cost is prohibitive to regular live-fire training, practice versions exist which are identical in operation but fire reloadable 9mm or 20mm tracers. The 20mm version is also a recoilless weapon and is favored by the Swedish army because of the added realism of the back-blast as compared to the "plonk" sound of the 9mm round (very similar to tapping your finger on an empty can). Projectiles There are several different projectiles for the AT4. Note that since the AT4 is a one-shot weapon, these projectiles are preloaded.
