my comment.....

many ace combat pilot never return home breathing bcoz of this aircraft....this plane is 1 hell of a kick ass...with its tough frame design, tonne of arsenal ( AIM-7F/M Sparrow, AIM-120 AMRAAM,  AIM-9L/M Sidewinder, AIM-120 missiles , Gatling gun)...its even equip with satlite destroyer missle (ASM-135 ASAT)

but, now its an old craft... radar & termol detecter had advance much to counter this palne... imagine during 8 nite, when this craft switch on the afterburner, a red hot flame can be seen through the sky... but even when its old day....its still king of the sky wit over 105 enemy aircraft killed without even a loss... but now, its need retire coz the raptor going to replace it...

then....? After the replacement?

please do continue.....

the F22 Raptor will replace the old F15 eagle....basicly all the rermaining eagle besome scrap metal...

Emm!Just as i expected from the aviation expert.Okay ill give some info too.

You know the machineguns on the aircract in WW2?Most of them are Ground Machineguns that is used in Ground combat.But on an aircraft,its Tripled times 2.Like most Allied Aircraft,they install 6 .30 caliber Machine guns on both wings.
Here are the Specs on the Allied Machinegun

Before the end of World War I, the U.S. Ordnance Department recognized that water-cooled machine guns took up too much space inside a tank. Consequently, the water-cooled M1917 was converted to an air-cooled model by surrounding the barrel with a perforated metal jacket.

As World War II approached, the Ordnance Department was committed to developing an air-cooled machine gun for infantry use. The result was the M1919A4.

At 41 lbs for gun and tripod, the M1919A4 was much lighter than the water-cooled M1917A1 (93 lbs for gun and tripod). On the other hand, the air-cooled weapon was unable to maintain the same level of sustained fire as the water-cooled M1917A1, and did not have the steadiness of accuracy as the heavier weapon. But its light weight and ease of set-up made it much more useful as an offensive weapon than the water-cooled guns.

In fixed defensive positions, however, the water-cooled M1917A1 saw much use in Korea. With anti-freeze in the water jacket, the heavy MG was more reliable in intense Chosin cold, as was particularly observed in the savage Reservoir battles. In any weather, the heavy was also more stable and, under intense attack, its greater sustained volume of fire was much appreciated.

Moreover, the A4 was crticized for slowness of set-up and vulnerability of crew. To meet these weaknesses, the M1919A6 was developed, and saw use in WWII, Korea and Vietnam.

The SIG SG.550 assault rifle had been developed by Swiss company SIG as a competitor for Swiss Army assault rifle contest in 1979 - 1980. SIG 550 had been derived from previous model SIG 540 and SIG 541, and was adopted as a Stgw.90 assault rifle in 1983, but due to financial reasons production began only in 1986. Currently, the Stgw.90 is a standard Swiss service rifle and also offered for export. "Carbine" version and subcompact assault rifle versions available in the form of SIG-551 and SIG-552 "Commando", respectively.

Basically, the SIG-550 is a somewhat lightened and refined SIG-540/541 rifle. SIG-550 featured AK-47 style action, gas operated, with gas piston attached to the bolt carrier, and with rotating bolt with two massive lugs. The recoil spring is located around the gas piston rod, above the barrel, and the bolt carrier attached to the gas piston rod by the mean of removable charging handle. The gas port has gas regulator with two different open and one closed position (latter for firing rifle grenades). The receiver is made from stamped steel and has two major parts, upper and lower, which are connected by pushpins. The barrel is screwed into the upper receiver. The trigger unit has a safety/fire selector switch on the left side of the receiver, with 3 settings: safe, semi-auto, full-auto. If desired, additional module could be installed in the trigger mechanism to allow 3-rounds burst mode. Rear sights are drum-type (like those found on Heckler-Koch rifles). SIG-550 has muzzle compensator/flash hider of NATO-standard diameter, so it is possible to launch rifle grenades from the muzzle. The SIG-550 has integral folding bipods under the handguard, and issued with side-folding, skeletonized polymer buttstock. Every rifle of SIG-550 family can be fitted with proprietary, quick detachable scope mount. Swiss Stgw.90 are often seen with 4X fixed power scope, export versions can be equipped with commercial telescope sights, ACOG or "red dot" sights, depending on customer preferences. SIG-550 also can be fitted with bayonet.

The carbine version of the SIG-550 is called SG-551 and has shorter barrel. SIG-551 can't fire rifle grenades. Even more compact rifle, SIG-552, is similar to SIG-551 except that it has shorter handguard and barrel. Version of the 551, called SIG 551 SWAT, is intended for law enforcement and is equipped with acessory rails on the forearm and comes with Trijicon ACOG optical sight and cheekpad on the buttstock.

The SG-552 "Commando" is a very compact assault rifle of the same class as russian AKS-74U or German HK53 and G36C. Due to the short barrel and resulting short gas piston rod, the main spring in SG-552 was relocated to the receiver, behind the bolt carrier group, so the bolt carrier of the SG-552 is not 100% similar to the bolt carriers of the SG-550 and 551.

All SIG-550/551/552 rifles are equipped with semi-translucent plastic magazines that can be clamped toghether for faster reloading.

Civilian verions of the SIG-550 and 551 are known as "Stgw.90 PE" in Switzerland or 500-SP and 551-SP when sold for export.

I just cant Stop Reviewing,Okay Keith.
This will be the last for today
Its one of our Favourite Rifle,the SA80

Caliber: 5.56x45 NATO
Action: Gas operated, rotating bolt
Overall length: 780 mm (709 mm in Carbine variant)
Barrel length: 518 mm (442 mm in Carbine variant)
Weight: 4.13 kg (with SUSAT optical sight and no magazine); 5 kg with SUSAT and loaded with magazine with 30 rounds of ammunition
Magazine capacity: 30 rounds
Rate of fire: 650 rounds per minute
Effective range: about 500 meters (with SUSAT sights)


The development of the SA80 (Small Arms for 1980s) system, which included two weapons - SA80 IW (Infantry Weapon) assault rifle and SA80 LSW (Light Support Weapon) light machine gun, began in the late 1960s when British army decided to develop a new rifle, which will eventually replace the venerable 7.62mm L1 SLR (British-made FN FAL rifle) in the 1980s.

When NATO trials were announced in 1977 to select a new cartridge, British state-owned Enfield Small Arms Factory developed its own small-caliber, high velocity round, which was more or less representing the US .223/5.56mm case necked down to accept 4.85mm (0.19 inch) bullet. When cartridge came out, Royal Small Arms Factory at Enfield developed a new weapon around it, initially designated as SA80-IW or XL65. This weapon, being somewhat similar in outline to the much earlier British Enfield EM-2 assault rifle, was internally quite different, and, basically, was more or less the US-made Armalite AR-18 rifle, put into bullpup stock and rechambered for 4.85mm cartridge. After NATO trials, which resulted in adoption of the Belgian SS-109 version of the 5.56mm cartridge, Enfield engineers rechambered XL65 for this cartridge and continued its development under the designation of XL70. Due to Falkland war new system was actually adopted only in 1984. Original SA80 weapons (both L85 and L86) were plagued with many problems, some being very serious. In general, L85 was quite unreliable and troublesome to handle and maintain, so, finally, in the year 1997, after years of constant complaints from the troops, it had been decided to upgrade most L85 rifles then in service.

The upgrade program, committed in years 2000 - 2002, was completed by the famous Heckler&Koch, which was then owned by British Royal Ordnance company (German investors bought the HK back in the 2002). About 200 000 rifles were upgraded into the L85A2 configuration, out of total 320 000 or so original L85A1 rifles produced. While official reports about the upgraded weapons were glowing, the initial field reports from the British troops, engaged in the Afghanistan campaign of 2002, were unsatisfactory. Most problems, however, were traced to improper care and maintenance of weapons, and for now the L82A2 performs fairy well both in Afghanistan and Iraq.

Other than the basic L85A1 variant, the SA80 IW also appeared in the shortened Carbine version, and in the manually operated L98A1 rifle, which got its gas system removed and a larger cocking handle attached. The L98A1 is used to train the army cadets for basic rifle handling and shooting skills, and the rifle is fired as a manually operated, straight pull magazine repeater rifle. The latest weapon in the SA80 family is the recently adopted L22 carbine, which is issued to tank crews of Royal Armoured Corps. This weapon is available in two versions, L82A1 and L82A2, the latter being fitted with additional Picatinny rail on the right side of front grip base.

The current L85A2 rifles are recognized as reliable and very accurate, especially when using standard issue SUSAT telescope sights. The drawbacks of the L85A2 are somewhat poor balance (which can be improved with installation of HK-made 40mm underbarrel grenade launcher), right-side only extraction and rearward placement of the fire mode selector.

Technical descrïption.
The L85 is a gas operated, magazine fed, selective fire rifle of bullpup layout.
The receiver of the L85 is made from stamped sheet steel, reinforced with welded and riveted machined steel inserts. The gas operated action has a short stroke gas piston, located above the barrel. The gas piston has its own return spring. Gas system has a three-positions gas regulator, one position for a normal firing, second for a firing in adverse conditions and the third for launching the rifle grenades (gas port is shut off). The machined bolt carrier rides inside the receiver on the two parallel steel guide rods, with the single return spring placed above and between the guide rods. The typical rotating bolt has 7 lugs that locks into the steel insert in the receiver, just behind the barrel breech. The charging handle is attached to the right side of the bolt carrier, and prior to A2 upgrade caused some problems by reflecting the ejected cases back into the action, thus causing stoppages. In the L85A2 configuration the charging handle was redesigned to avoid such problems. The charging handle slot is covered by the spring-loaded dust cover. The bolt and its extractor claw also were upgraded in the L85A2, to achieve more reliable extraction of the spent cases.
The trigger / hammer assembly of the L85A1 is also typical for a modern bullpup rifle, with the long link from the trigger to the hammer unit, located in the buttstock. The hammer assembly of the L85A2 was redesigned to introduce a slight delay before the hammer release when the gun is fired in the full auto. This did not affected the cyclic rate of fire but improved the reliability and stability of the weapon during the automatic fire. The fire mode selector is located at the left side of the receiver, well behind the magazine housing, and allows for single shots of full automatic modes of fire. The cross-bolt safety button is located above the trigger.
The barrel is rifled for a NATO-standard 5.56mm ammunition, with 1:7 twist, and is fitted with a NATO-standard flash hider, which allows to launch the rifle grenades from the barrel.
The L85 is fed using NATO-standard (STANAG) magazines, similar to M16 type magazines, with the standard capacity of 30 rounds. Early L85A1 steel magazines caused a lot of troubles, as well as a magazine housing itself, which had a thin walls that could be easily dented, thus blocking the magazine way. Both magazines and its housings were upgraded in the L85A2 configuration.
The standard sighting equipment is the 4X SUSAT (Sight Unit, Small Arms, Trilux) telescope, with illuminated reticle. The SUSAT is mounted on a quick-detachable mount at the top of the receiver, and features an emergency backup open sights at tits top. The SUSAT allows for an accurate fire (mostly in single shots) out to 400-500 meters. For a second-line troops an alternative sighting system is available, that consists of the removable front post sight with high base and post protection "ears", and a detachable carrying handle with built-in diopter rear sight.
The L85 can be fitted with the proprietary knife-type multipurpose bayonet. L85A2 rifles also can be fitted with 40mm under-barrel grenade launcher, using special handguard. Launcher is made in Germany by Heckler-Koch

tau.......commando...the terrorist 4~2 in the counter strike rite?...... SA80....1 of my fav all time........byk jua boy......rajin ko klau bahagian weapon......wait till an intelligent agency read this...well,...u predict the end of this story by own...till then...lets continue..

Lets Continue then
Gun of the Day is    BERETTA
The handgun section is not complete without this legendary pistol








Caliber: 9x19mm Luger/Para; also .40SW in Mod.96 and 9x21mm IMI in mod.98
Action: Double action
Overall Length: 217 mm (197 mm Compact versions)
Barrel Length: 125 mm (109 mm Compact versions)
Weight Unloaded: 950-975 grams, depending on model
Capacity: 15 rounds (all 92 and 98 models except compact); 13 rounds (92 Compact); 11 rounds (mod.96 in .40SW); 8 rounds (92 Compact type M)

Originally designed for the Italian army and police, the Model 92 pistols earned most of their fame (both good and bad) as the standard sidearm of the US military. It was developed between 1970 and 1975 as a possible replacement for ageing Beretta M951 pistol, and entered production in Italy in 1976.
First adopted by the Brazilian army in 1977, this pistol was later adopted in Italy in its Model 92S, “SB”, and finally “F” modifications. The US military adopted the Model 92SB-F (later renamed to model 92F) in 1985, as a result of the highly controversial XM9 trials. In the late 1980s and 1990s, these pistols were also adopted in France. It must be noted that, while being entirely adequate as a combat pistol, the Beretta 92 is somewhat bulky for its caliber and magazine capacity, thus less suitable for users with average or smaller hands. Other than the basic 9mm, Beretta also makes these pistols in other calibers, such as .40 S&W (model 96) and 9x21 IMI (Model 98, available for civilian users in certain European countries, including Italy). Beretta also makes a wide variety of models based on the same design; these include not only variations in finishes and sights, but also different trigger types (DA/SA, DA/SA with decock only, DAO, DAO with manual safety).

Beretta 92 pistols are short-recoil operated, locked-breech weapons with an aluminium frame. The locking system is of the Walther type, with a vertically-tilting locking piece located below the breech area of the barrel. The trigger is double-action, with an exposed hammer. Original Model 92 pistols had a frame-mounted safety which was applied only when hammer was cocked; all subsequent pistols (except for some limited production civilian-only sporting models) either had a slide-mounted safety lever or no safety lever at all. On some pistols, such as the Model 92G adopted in France, the levers do not lock themselves in the lowered position but return to the “fire” position once released – their function is limited only to safe decocking of the hammer. Some other models, such as the Model 92D, are double-action-only pistols with no manual safety or decocker. All pistols of current production are fitted with an automatic firing pin block safety. Magazines are double stack, with the magazine release button located in the base of the trigger-guard on all 92-series pistols made since 1981. Sights on service models are of fixed type, with a dovetailed rear blade, usually with high-contrast inserts.
With the introduction of the Model 92FS in the late 1980s, another unusual safety feature was fitted in the form of an enlarged head to the hammer pin. The purpose of this safety is to prevent the rear of the slide from flying back into the firer’s face in the case of the slide failure. This happened several times during the earlier years of Model 92F service in US military, apparently because of metallurgical problems, combined with the “built-in” weak points in the slide where the locking block cuts are made. Recognizing these weak points, the US INS (Immigration and Naturalization Service) requested Beretta to make their model 96 (.40 S&W caliber version of Model 92) with reinforced slides. This resulted in appearance of the Model 96 Brigadier pistols, and, later on, the same modification was applied to 9mm pistols, available as Model 92 Brigadier. Beretta also produced a number of compact versions of their basic, full-size Model 92 variations. These compact versions had shortened grips, slides and barrels; Compact Type M versions also featured single-stack magazines with appropriately thinned grips. At the present time, Beretta no longer makes Compact versions of the Model 92; in the firm's product line these were replaced by the entirely different Model 8000 Cougar pistols.

Below is a brief list of most important modifications and versions produced in the 92-series over last 30 years.
Beretta 92S (1976) – first modification of the basic model 92, with non-ambidextrous slide-mounted safety/decocker and magazine release button set low in the left grip panel. It was replaced in production by the Model 92SB.
Beretta 92SB (1981) – further evolution of model 92S, initially designated Model 92S-1, later designated 92SB with the introduction of the firing pin block. The manual safety is ambidextrous, the magazine release relocated to the base of the trigger-guard. Discontinued since 1991.
Beretta 92SB-C (1981) – Compact version of the model 92SB. Overall length was 197 mm, barrel length 103 mm, magazine capacity 13 rounds (also accepted standard 15-round magazines).
Beretta 92SB-C type M (1983) – slimmer version of the model 92SB-C, with a single-stack magazine which held only 8 rounds.
Beretta 92F (1984) – initially designated 92SB-F, later renamed 92F. Evolved from the Model 92SB during American XM9 trials, with a slightly reshaped grip and trigger-guard, also a different finish. The barrel bore and chamber are chrome-plated.
Beretta 92G (1989)- the so called "Gendarmerie" version, created at the request of the Gendarmerie Nationale de France. Also manufactured under licence in France by GIAT Industries as the PA MAS G1. The pistol is the same as the model 92F except for the operations of the lever, which lost its safety lock function and is used only to safely decock the hammer.
Beretta 92FS (1989) – a minor modification of the Model 92F, with an enlarged hammer pin head which prevents the slide from flying back in the case of breakage. Presently, all US M9 pistols are modified to 92FS standard.
Beretta 92FS-C (1989) – compact version of the Model 92FS, similar in dimensions to earlier model 92SB-C. No longer made.
Beretta 92FS-C type M (1989) – single-stack version of Model 92FS-C, magazine capacity 8 rounds. No longer made.
Beretta 92DS (1990) – Double Action Only version of the Model 92FS, with spurless hammer and manual safety.
Beretta 92D (1990) Double Action Only version of the Model 92FS, with spurless hammer and no manual safety levers.
Beretta 92FS Brigadier (1996) – version of the Model 92FS with a reinforced, thickened slide; another change is that the front sight is not integral to the slide, but is dovetailed into it
Beretta 92FS Centurion (1996) – version of the Model 92FS with a shortened barrel and slide, the frame is the same as on the Model 92FS. Overall length is 197 mm, barrel length is 103 mm, magazine capacity 15 rounds.
Beretta 92 Vertec (2003) – version of the Model 92FS that addressed constant complaints about the excessive grip width of Model 92 pistols. The backstrap of the grip on Vertec models is made more linear; another change is the addition of an integral Picatinny rail to the frame.
Beretta 90two (2006) - a most recent face-lift version of the basic Model 92 design. Key changes are modular one-piece grip panels (available in various shapes), integral Picatinny rail under the barrel (with cover), restyled slide and integral recoil buffer built into action.

How to field-strip (disassemble) Beretta 92 pistol: 1) remove the magazine by pressing the magazine release button; 2) check that the chamber is empty; 3) pull the slide all the way back and lock it with the slide stop lever; 4) depress the takedown lever stop, which is the small button located of the left frame above the trigger guard; 5) while holding the button down, rotate the takedown lever (located at the right side of the frame) downward about 90o ; 6) pull the slide slightly back to disengage the slide stop, then carefully push it all the way forward and out of the frame; 7) remove the return spring by pushing its head slightly forward and then pulling it out of the detent in the barrel; 8) push the locking lever pin (protrudes backwards from below the barrel breech area), then lift up the barrel from the slide.
Reassemble in reverse order.

plane of the day is the: SUPERMARINE SPITFIRE of the RAF

Type Fighter
Manufacturer Supermarine
Designed by R. J. Mitchell
Maiden flight 5 March 1936
Introduced 1938
Retired 1952, RAF
Primary user Royal Air Force
Produced 1938–1948
Number built 20,351
Unit cost £15,000
Variants Seafire
Spiteful

possibly the most iconic plane during the world war... The elliptical wing design which gave this plane its trademark look acually for giving an aerodinamic & streamline design which gave an agility of a fighter 1 step ahead than any fighter plane during its period....

this plane gain its reputation during the "BATTLE OF BRITAIN" where this plane come face to face with the tough Luftwaffe's Messerschmitt Bf 109


Some inherent advantages helped the Spitfires win many dogfights, most notably maneuverability: the Spitfire had higher rates of turn than the Messerschmitt. Good cockpit visibility was probably a factor as well, as the early Bf 109s had a narrow enclosure with heavily-framed, panelled cockpit windows

but the biggest weaknest of this plane is the use or carborater engine, which mean this plane can't do the negetive-g turn (the plane doing an upside down monuevabilities)...while the BF-109 wit its fuel injection can do it...so most of the battle invovled by the pilot's experience to win any dogfighting

Armament
Guns:

2× 20 mm (0.787 in) Hispano Mk II cannon, 60 (later 120) shells per gun
4× 0.303 caliber (7.7 mm) Browning machine guns, 350 rounds per gun
Bombs:

2× 250 lb (110 kg) bombs


although does't pact a puch.... but still this aircraft win by it technological advance imbeded in it...

well....I can say this board seems to go well and its track didn't goes out.....hahaha I dunno much about guns but I am happy to learned it! Keep it up!

guess so,...but i dun giv much hope that this fourm will last long....juz cross ur finger that syuu is still able to spend much time surf inter after next month...

I wanna resighn on these guns for awhile.Wanna Make a new board which is MARTIAL ARTS P/sont talk crap!Only discuss about Techniques and how to defeat people!

Hahahaha~ good point there!
