Hm.......
Sometimes....i wonder......what is wrong with reading comics? Some give you a sense of humour. Anyways......some people don't understand my feelings.....so i'm going to talk about some weapons now.

HK MG3 or also known as the Rheinmetall MG3.
The MG 3 is a German general purpose machine gun chambered for the 7.62x51mm NATO cartridge. The weapon's design is derived from the World War II era MG 42 universal machine gun that fired the 7.92x57mm Mauser round.
The MG 3 is an automatic, air-cooled, belt-fed short recoil-operated firearm. It features a roller locked bolt mechanism that consists of the bolt head, a pair of rollers, the striker sleeve, bolt body and return spring. The bolt is locked securely by a wedge-like striker sleeve, which forces two cylindrical rollers contained in the bolt head outward, and into corresponding recesses in the extension of the breech of the barrel. On firing, both the barrel and barrel extension recoil to the rear compressing both rollers as they are cammed inward and out of their sockets by fixed cams, unlocking the bolt head. The bolt carrier and bolt then continue to the rear together guided by fixed guides while the barrel and barrel extension return to battery. Upon return of the bolt forward, the impact of the rollers against the camming surfaces on the breech carry the rollers from their seats, and, together with the surfaces on the striker sleeve, force the rollers outward, locking the bolt head into the barrel extension and ensuring a complete lock. The bolt also houses a spring-loaded casing extractor and ejector. Ejection is carried out when the ejector strikes the buffer head, sending a push forward through the ejector bar, which hits the ejector pin. This pin pushes the top of the base of the cartridge, which is still held by the extractor at the base, causing the empty casing to rotate and eject downward through the ejection chute.

The machine gun has an automatic-only trigger mechanism and a cross-bolt safety in the form of a button that is operated by the shooting hand (in its "safe" position the bolt release is disabled). The weapon fires from an open bolt.

The MG 3 feeds from the left side through a feed block using metal, 50-round continuous-link DM1 ammunition belts (which can be combined by cartridge) or disintegrating-link M13 or DM6 belts. In the light machine gun role, the MG 3 is deployed with a 100-round belt fitted inside a synthetic ammunition drum developed by Heckler & Koch that is latched on to the left side of the receiver. The rear wall of the drum is transparent and serves as a visual indicator for the amount of ammunition available. The feed system operates through a feed arm that is housed in the feed cover. Two feed pawls are linked to the front end of the arm by an intermediate link and move in opposite directions, moving the belt in two stages as the bolt moves back and forward during firing.

The MG 3 has a quick-change, chrome-lined barrel with 4 right-hand grooves and a rifling twist rate of 1 in 305 mm (1:12 in). The barrel is integrated with the barrel breech. The barrel should be changed frequently during sustained firing. The gun is cocked and the barrel catch on the right of the barrel shroud is swung forward. The breech end of the hot barrel swings out and can be removed by elevating or twisting the gun. A fresh barrel is then inserted through the barrel catch and the muzzle bearing. When the catch is rotated back the barrel is locked and the machine gun can resume firing. Both the receiver housing and ventilated barrel casing are made from pressed sheet steel. A muzzle device is mounted at the end of the barrel and it acts as a flash suppressor, muzzle brake and recoil booster.

The machine gun is equipped with a synthetic polymer stock, a folding bipod and open-type iron sights (sliding rear U-notch on a ramp with range settings from 200 to 1,200 m). A flip-up anti-aircraft sight is also provided.

In a stationary, heavy machine gun role the MG 3 is mounted on a buffered tripod called a Feldlafette and outfitted with a periscope sight that can be used to engage indirect targets.

FGM-148 Javelin
The FGM-148 Javelin is an American-made man-portable anti-tank guided missile fielded to replace the Dragon antitank missile.

Javelin is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a top-attack flight profile against armored vehicles (attacking the top armor which is generally thinner) but can also take a direct-attack mode for use against buildings or fortifications. This missile also has the ability to engage helicopters in the direct attack mode.[1] The missile reaches a peak altitude of 150m in top attack mode and 50m in direct fire mode. The missile is equipped with an imaging infrared seeker. The tandem warhead is fitted with two shaped charges: a precursor warhead to detonate any explosive reactive armor and a primary warhead to penetrate base armor. The Javelin was used in the 2003 Invasion of Iraq, with devastating effects on the Iraqi version of T-72s and Type 69 tanks.

The missile is ejected from the launcher so that it reaches a safe distance from the operator before the main rocket motors ignite; a "soft launch arrangement". This makes it harder to identify the launcher and allows it to be fired from within buildings; however, back-blast from the launch tube still poses a hazard to nearby personnel. Thanks to this "fire and forget" system, the firing team may move on as soon as the missile has been launched.

The missile system is carried most often by a two man team consisting of a gunner and an ammo bearer, although it can be fired with just one person if necessary. While the gunner aims and fires the missile, the ammo bearer scans for prospective targets and watches for threats such as enemy vehicles and troops.

Luger P08
The Luger uses a toggle-lock action, which utilizes a jointed arm to lock, as opposed to the slide actions of almost every other semi-automatic pistol. After a round is fired, the barrel and toggle assembly (both locked together at this point) travel rearward due to recoil. After moving roughly one-half inch (13 mm) rearward, the toggle strikes a cam built into the frame, causing the knee joint to hinge and the toggle and breech assembly to unlock. At this point the barrel stops its rearward movement (it impacts the frame), but the toggle and breech assembly continue moving (bending the knee joint) due to momentum, extracting the spent casing from the chamber and ejecting it. The toggle and breech assembly subsequently travel forward (under spring tension) and the next round from the magazine is loaded into the chamber. The entire sequence occurs in a fraction of a second. This mechanism worked well for higher pressure cartridges, but cartridges loaded to a lower pressure could cause the pistol to malfunction because they did not generate enough recoil to work the action fully. This resulted in either the breechblock not clearing the top cartridge of the magazine, or becoming jammed open on the cartridge's base.[2]

In World War I, as submachine guns were found to be effective in trench warfare, experiments with converting various types of pistols to machine pistols (Reihenfeuerpistolen, literally "row-fire pistols" or "consecutive fire pistols") were conducted. Among those the Luger pistol (German Army designation Pistole 08) was examined; however, unlike the Mauser C96, which was converted in great numbers to Reihenfeuerpistolen, the Luger proved to have an excessive rate of fire in full-automatic mode.

The Luger pistol was manufactured to exacting standards and has a long service life. William "Bill" Ruger praised the Luger's 55 degree grip angle and duplicated it in his .22 LR pistol.

M40 Rifle
The M40 is a bolt-action sniper rifle used by the United States Marine Corps.[1] It has had three variants — the M40, the M40A1 and the M40A3. The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, and the A3 in the 2000s.

Each M40 is built from a Remington 700 bolt-action rifle, and is extensively modified by USMC 2112 (Armorers) at Marine Corps Base Quantico, using components from a number of suppliers. New M40A3s are being built, and A1s are upgraded to A3s as they rotate into the armory for service and repair. The rifles have had many sub-variations in telescopic sights, and smaller user modifications.

The original M40 was a military type-classified version of the Remington 700; it was factory-made, and had a one-piece wooden stock. The M40A1 and A3 switched to fiberglass, with new scopes. The trigger pull on both models (M40A1/A3) is 3 to 5 lb (2.3 kg).
