MODEL 6 | COMBAT GRENADE
Model 6 Specifications-
The Offensive variant of the Model six is the primary, and most common variant of the Model six grenade currently produced. Primarily it retains almost all the features of the Model Six Defensive Grenade, but does not contain any pre-formed fragments. As with all Offensive grenades the primary damage is done by the concussive force and heat of the explosive, yet has a limited casualty radius so as to not injure advancing troops. Because the body casing is made of lightweight polymer the resulting fragments have an exceptionally short radius, and rarely travel past three meters from the point of detonation, meaning that the five-meter casualty radius is technically a ‘hard’ radius allowing for troops to use it in relatively close quarters without fear or injury.
The M6-IS is primarily an Impact (M9) fused grenade designed for dealing with bunkers or other enclosed targets. On impact the grenade simultaneously produces a brilliant flash of light, and a large volume of dense smoke. The burning components scatter over a fairly large area and will burn for approximately five minutes at around fifteen hundred degrees Celsius. The bright flash of light produced by the grenade on impact instantly blind any nearby enemies and the thick choking smoke that’s released immediately afterwards further degrades any enemies their ability to fight or navigate within a confined space. The incendiary fragments produced by this grenade are capable of igniting almost any combustible material it touches and can be used with a timed fuse (M8) for use in the destruction of equipment or vehicles.
The Less Lethal option of the Model Six is perhaps the most uncommon development of the series, as the requirements for its use require both different materials and different internal construction. The M6-LL uses a Hardened rubber body that is pre-scored around its equator to allow for quick separation of the grenades halves. A standard fuse is used, but other than the common low-pressure detonator, no other explosive is used. The hollow of the case is filled with one hundred-and-fifty, five millimeter (nominal) hardened rubber balls. These rubber projectiles are considerably less lethal than their steel counterparts, and can be mixed with an irritant powder to provide twice the dispersing or subduing capability. Because it uses a standard fuse the report and flash produced are noticeable and tend to have a Flash-Bang like effect on rioters within a certain distance of its detonation. Though there is a slight fire hazard with the use of this (and any grenade) proper training and education should reduce any such risks encountered by the operator.
The training practice Grenade was designed for use in throwing an operating instruction of the Model Six grenade. The M6-TP is the only Metal cased Grenade in the Model 6 line; as such it is heavily reinforced to match the weight of a loaded Model 6 Defensive Grenade. Traditional ‘live’ M8 or M9 fuses are used, and the reinforced aluminum body is perforated to allow the report and smoke generated to be observed from a distance. Though designed to be reusable, they do not have the benefit of having their color injection molded into them, and such must be occasionally repainted to retain their proper marking scheme. Though some small fragments are ejected from the bottom perforations of the grenade the safety radius is remarkably low allowing for use in most training ranges without incident.
The Model 6 Series of grenades was developed to replace and improve on the formerly adopted Mark Three Defensive Grenade. The Mark Three was Amastols first attempt at a indigenous grenade and though nationalistic policies forced its adoption its actual combat effectiveness was extremely limited. The now aging Mark Three (beyond its technical issues) only filled one role within the Royal Guards, making it only one small solution to many varied and large roles encountered by military and law enforcement professionals. As such, the Mark Three attempted to do too many things at one time and subsequently failed. Improving, Modernizing, and Re-utilizing the ideas that worked in the Mark Three lead to the creation of the new series of grenades, one that could be made to fill many different roles with little change in manufacturing facilities for each variant.
Though many different variants exist for the Model Six they all share many common features and components, which help keep the cost of manufacturing down significantly. This commonality also allows for the continued development and testing of variants for foreign and domestic powers without the high cost of ‘rapid’ prototyping, as common components can be utilized, arranged and demonstrated quickly and cost efficiently. As such it is likely to see the catalog of variants for the Model Six continue to grow in the coming years. The model Six has served with distinction as the primary combat grenade for Amastoli military the last two years.
The Model Six grenade uses q new generation of electronic fuses, using primarily the precision timed (M8) or Impact (M9) fuses, however other options are available. The low profile advanced fuses use a spring-powered Coil-style current generation system similar to the reverse operation of a solenoid. This system is to be referred hereafter to as the ‘striker’ allows the grenade to operate in a completely safe mode for years at a time without worry of shorting out or ‘cooking off’ due to degradation of a battery or chemical system. The necessary current required for the operation of the grenade is amplified by several small capacitors arranged in series in order to provide ample voltage and amperage to ignite the low sensitivity booster charge. The amplified current is then passed onto the Main Processing Unit or MPU (a fancy name for a hardened timing and switching unit) which then releases the current at the correct time or impulse depending on the fuse to the ‘dead stop.’
The ‘dead stop’ is the final ignition safety on the Model 6; it is essentially a Normally Open (NO) Switch connected to the travel safety. This means that in its transport and storage state even if the pin is pulled (or melted) and the striker released, that the grenade remains safe from unintended detonation. If the travel safety is up, the circuit cannot be completed, and the dead stop cannot operate. Therefore any current that enters the system (either stray current, internal malfunction, or some other means) cannot reach the detonator through any means. If the travel safety is down however; the current passes through the now closed switch into the two detonation leads and ignites the low-sensitivity detonator below.
The use of electronic fusing allows for exceptional timing accuracy, reliability, and repeatability compared to chemical fusing. Chemical fusing by its very nature is energetic, and subject to variations in pressure, temperature, and humidity. Electronic fusing also allows for the use of lower sensitivity explosives increasing the safety and storage life of munitions significantly. Because no batteries are used in the M8 or M9 fuses there is no damage of corrosion, and the entire operating section (sans the ‘striker’) can be resin encased to make it immune to humidity and water concerns. This waterproofing also allows the Model Six to be used as Anti-frogman Munitions, and by Marine, and Combat Divers who must rely on their equipment to operate regardless of water. Combined with the multiple ignition safeties found in the Model Six they can be effectively considered inert until use. What this means to the user is that regardless of where you are fighting, or what you just crawled through, the Model six will be ready to function reliably, and safely at any time.
The Safety ‘Ring’ or Pull Ring is constructed of high strength polymer with two lateral reinforcements to prevent any twisting, and reduce the strain on the material if it is pulled from the grenade with excessive force. Though the polymer used in the forming of the ‘ring’ is rated to take much more force than a normal human can produce, the system was designed for durability and strength so as to better survive in the field. The lower section of the ‘Ring’ is and elongated D-shaped and designed for use with winter gloves on allowing its instant use in the harshest of climates. The safety pin is formed form a single piece of the same polymer used to construct the ring. The semi-circle shaped piece of high-tech polymer is folded in half with the ring at one end then heated to forma continuous ‘pin.’ Once inserted into the fuse assembly the end of the pin is heat and pressure formed into a button shape, and pre-scored so that on pulling the rung from the grenade the polymer pin shears cleanly, allowing the pin to fall away easily.
The safety lever used on the Model Six is made of the same polymer as the case of the grenade. This due to its lightweight nature and toughness allows the grenade to maintain a very long shelf life without fear of corrosion or fatigue. Its lightweight form also allows for a very strong and short release time reducing the potential for the grenade to misfire or only partially release the ‘striker’ on throwing. By using polymer in the ring, pin, and safety lever the weight and acoustic signature of the grenade are reduced significantly. Though this is less of a concern on the open battlefield, in urban combat it may make the difference between life and death for those attempting to secure a location. The aforementioned safety switch, which is built into the top of the fuse, also acts as a physical barrier that helps keep the grenade from releasing its safety lever while in transport. The safety pushes up against the far side of the safety lever preventing the lever from lifting or flying off even if the pin is pulled. This simple utilization of leverage allows for the grenade to be carried into the field with both safeties active, until they soldier is read to use it. To operate the soldier simply grips the grenade normally and pulls down on the switch with his index finger or thumb then pulls the pin and throws as per any spherically cased grenade. Allowing for the weapon to be transported safely, and yet be made ready for throwing in under a second, with or without gloves on.
The Model Six Defensive Grenade (the fragmentation variant of the Model Six series), is filled with two thousand heat-treated hardened-steel projectiles of (nominally) two-point-five millimeters each, arranged in two rows. The projectiles are embedded in a resin matrix that helps support both the projectiles, and reinforce the outer casing. The Model Six is filled with a low sensitivity; high explosive material that polymerizes once it sets in the grenade to form a shock resistant solid high explosive. This high explosive requires a booster to initiate, and can therefore be safely carried in the field as even penetration by a bullet or the heat from a fire will not detonate the munition, as the explosive will liquefy long before it detonates. The detonator though more sensitive than the High Explosive is not as powerful and is protected by a perforated brass tube in the very core of the grenade. The perforations allow for rapid initiation of the explosive at multiple vectors increasing detonation reliability in the field. A ’splinter disk’ is interposed between the fuse/detonator and the outer casing along the equator of the sphere. This splinter disk helps refract some of the explosive force of the grenade allowing for a much more equal and consistent distribution of fragments regardless of its detonation angle. This means that no matter how the grenade lands the overall projectile density remains consistent in a spherical pattern.
The body of the Model Six series is produced from the same polymer material used on many of our most popular small arms. This 35% Glass-Fiber Reinforced Polymer is both exceedingly tough, and remarkably lightweight compared to similar aluminum, or steel casings. The colorings on the grenade (both the type band, and overall case colorings) are progressively injection molded into the grenade itself making it impossible to wear off in the field. This means quicker identification of grenade types, and better safety for the use due to identification reliability. The body casing aggressively is stippled in an irregular pattern for improved grip with wet or muddy hands; the raised reinforcement ring in the center improves orientation in the hand even in complete darkness, and its smooth surface prevents any ‘hang-up’ when throwing the grenade underhand. Its nearly spherical dimensions without the safety lever attached means that the grenade can be thrown for quite some distance depending on the skill of the user, and can be easily rolled for use in urban combat.
The grenade can be fused from either the top or the bottom as the case is vertically symmetrical, or with an adapter can be ‘daisy chained’ to produce an improvised demolition charge. The bottom plug on the grenade has a wide and deep cut out allowing it to be removed with various items found in the field such as a small coin, a bayonet, or a weapons take-down tool. More often however, the bottom plug can be unscrewed to insert a polymer stake for use of the grenade as an improvised mine or booby-trap. Rifle-grenade conversions have been investigated but are not at this time currently available.
The Model Six was developed with the mistakes of the past in mind. Instead of developing just one type of grenade ARGUS developed a common housing and fusing system that could be used to produce as many variations as possible within a given frame. This flexibility has allowed ARGUS developers free reign in the development and implementation of various variants of the Model Six. Designed for strength and reliability, the Model six is a new generation of offensive munitions, designed to take the simple hand grenade fully into the twenty-first century. Its Long shelf life, and safety in transport makes the model Six a boon for logistics and command authorities, its reliability and durability make it beloved to the solider, and its quiet operation, and lethality make it feared by its targets.
