History The SOV.17 was originally designed to replace the SOV.6 as the principle infantry fighting vehicle sold by Kriegzimmer, and was a completely independent project, seperated from the Fuermak and its design goals. During the early months of the research Kriegzimmer was introduced into a competition for an infantry fighting vehicle for the Spizanian Army, and thus it began to work in tandem with the goals of said institution, making it a quasi-cooperative work. Nevertheless, the SOV.17 still left with a Kriegzimmer look to it. The basic design goals were as follows: the ability to carry eight passengers, a 35mm autocannon and two anti-tank guided missile launchers. By the completion of the project in time for the Spizanian Army to make its decision it would fulfill all three requirements in some form or another, although the main armament would take an interesting twist for better or for worse. Nevertheless, it would become an air droppable and formidable armoured fighting vehicle, designed for its purpose and for its porpose only - to provide infantry support and ferrying capabilities.

The SOV.17 would never see production for the Ejermacht. Instead, the Arica. I Shalmanesar was chosen, with its ability to carry twelve soldiers if need be, not including the three crew members, and for its sufficient armament to protect itself until it arrived at the drop point for the mechanised infantry. The Arica. I began production in late June 2016 and would see its first deployments in August 2016, ready for combat by early September - a full month before the original deploy date, which was October 2016. However, local production was alotted fully to the Shalmanesar and SOV.17 would only see foreign export by Kriegzimmer. For foreign export the SOV.17 would begin to roll off the production line by August 2016 and it would see thousands of units shipped off to foreign armies. It was expected that most nations fielding the SOV.6 would be quick to exchange their old designs for the newer models, and even sell off their older designs to smaller nations. The success of the SOV.6 made Kriegzimmer optimistic that it would sell the SOV.17, even if its intended market, Spizania, failed to choose it after the infantry fighting vehicle trials.

The Etymology of the name can be traced back to General Elijah Ejíard, commander of the 14th Arca Division at Quintin's Barn in 1952. Ejíard is one of the more well known Gerfaanlichi commanders that served during the early years of the war, before Gerfaanlich was forced to leave the mainland and remain an independent colony in the region of Haven. Ejíard was also one of the later masterminds behind further developement in genial Gerfaanlichi armour developement which was exported to Weigar and Soborguntia during the later years of the war. He is one of the few 'rebel' [Gerfaanlich is still considered a provence in rebellion] generals who have been honored by having their names installed as a vehicle class, and in fact the first in the Empire's vehicle taxonomy. However, there is good reason for his name being used, including his genius use of his division to isolate and destroy three Macabee divisions during the battle, ending in over fifty vehicles outright destroyed. His actions during the entirety of the war are studied in war colleges around the world. In any case, he would soon be embosed in history as the giver of the name for this well designed infantry fighting vehicle.

Armament:
The Ejíard Infantry Fighting Vehicle is topped with an unmanned turret, carrying a one ton compulsator, and a six barreled dual-caliber gatling gun taking advantage of the same technologies used on the Conhort Mk. II close-in weapon system for current and future Kriegzimmer shipping. The gun's stealth rail support, mass attuned shroud cools the six barrels with a forced air cooling system, avoiding high end coolants like liquid nitrogen. Three of the six barrels are 25mm in diameter and the other three are 35mm in diameter. An onboard fire control systems decides on which calibre to use for which job, and in one burst only one calibre is fired. The 25mm can be used for low armoured targets, like infantry and soft-skinned vehicles, while the larger and harder hitting 35mm would be used for armoure fighting vehicles in the same tonnage area. Each barrel is a pentagon in shape, with five accelerating rails per barrel. For maintenance each rail can easily be slipped out and exchanged with a new accelerating rail, or fixed if need be. The maingun is fed by two boxes on either side of the guns, fed by seperate feed carousels. There are nine hundred 25mm tungsten core anti-personnel bullets in a basket to the right of the turret, and six hundred 35mm laser fused penetrators in a basket to the left. The main gun, mounted on two independent wheel trunnions can elevate to roughly +60 and -10 degrees, making use of an independent module to replace the mantlet. The feeds, being radially symmetric would have no problems feeding the gun at these angles.

On the right side of the turret is a side-mounted dual missile launcher, designed to carry the Pilum enhanced fiber optic guided missile [EFOGM], used for extended range targets. The nozzleless integrated rocket booster and a ducted ramjet engine the Pilum has a range of eight kilometers. The generally top-attack missile can penetrate roughly 1,200mm of armour using a low massed, shallow cone shaped charge. The Pilum was originally designed for use as a gun launched EFOGM for the Arca. IV Nakíl Main Battle Tank, but can be made larger to fit the launch pods on the SOV.17 Ejíard.

The infantry in the rear can fire from four gun ports installed on the Ejíard's rear release door and from the sides to protect the vehicle from infantry threats on all sides, given that even the vehicle's two-man crew is buried in the hull. The gun ports are large enough to fit the muzzle of a lightweight squad level machinegun, as well as assault rifles and anything of similar size. Admittedly, the idea is not unique to the Ejíard and resemble the Mekugian designed advance firing ports [AFP] present on the Arica. I Shalmanesar, or the APV-30 Jaguar as it's known by in the Mekugian Armed Forces. Stabalisation is achieved through offering a pintle mount for the guns, as well as verticle stabalisation and an integrated recoil attenuation service to make fire accurate, effective and comfortable. Two permament 7.62mm or 5.56mm machineguns can be mounted permanently on the pintle mounts if required.

Armour:
The vehicle's primary defeatable opponents consist of infantry, soft-skinned vehicles and light armoured fighting vehicles, including other infantry fighting vehicles and armoured personnel vehicles. Keeping that into consideration requires an armour that can take the punishment from these vehicles, but another major goal was for the SOV.17 to be air droppable, which would require a lighter armour. The scheme was dubbed 'Geop' and consists of a light 20mm perforated front plate of armoured steel [RHA], backed by ~20mm of rubber, which was then spaced 10mm away from a 60mm front plate of honeycombed aluminum, spaced from a back plate of 100mm of aluminum. The 10mm space between them is occupied by rubber. The idea is fairly simple. The front steel plate is designed as a standoff plate against high explosive anti-tank [HEAT] projectiles and large calibre infantry munitions >15mm, and the rubber would cause a non-explosive expansion and compression reaction against penetrating targets, either breaking up the heat warhead or enducing yaw on a small calibre penetrator. The aluminum/rubber/aluminum laminate is the principle non-explosive reactive armour composition of the vehicle, designed to offer a lightweight alternative to steel, and still put up a strong reaction against an overpenetrating target - overpenetrating meaning that it penetrated the steel/rubber buffer.

The entire armour would be ~220mm thick at the thickest point, but would weigh about two-fifths of a similar plate of rolled homogenous armour. Simultanously it would provide about ~2.1 worth of rolled homogenous equivalent at 60 degrees obliquity, meaning the weakened sections and turret corners offer around 528mm of RHAe against kinenetic energy weapons [KEW], and the upper glacis around 462mm of RHAe, given that the two are of uniform thickness. Further values for the entire vehicle can be see below. The same thickness and ame angle against HEAT should render a rolled homogenous equivalent ratio of ~8:1. Both ratings can be read below in the combat vehicle specifications, including real thickness, RHAe versus kinetic energy weapons and RHAe versus chemical energy weapons.

The roof of the turret is also covered by the same light explosive reactive armour bricks that protect the Nakíl main battle tank. The system uses 7.6 x 11.9mm blocks with two parallel plates lined with explosives underneath. The plates are designed to explode outward, offering ~four times the protection as RHAe [against HEAT] given the ~90 degree sloping of the roof. Nevertheless, the roof mounted ERA appliqué offers an interesting, innovative and effective method of negating the advance of smaller submunitions used in tank killing. Nevertheless, the system is defeated through the use of the tandem warheads on top attack anti-tank guided missiles – but some protection is better than no protection. For further protection versus HEAT one can apply appliqué slat armour for little weight addition.

Active Protection System:
Given the general trend towards increasing the actual thickness of armour coming from main battle tanks and other armoured fighting vehicles, and the same trend towards increasing the size of one's armament, lightweight vehicles are being forced to look elsewhere for protection - steering away from heavy and thickness effective armours. Armament designers are looking more and more into active protection systems. The first Imperial vehicle to include an active protection system since the 1950s was the Nakíl main battle tank, weighing 71 tons. At just over 23 tons one could say that the SOV.17 Ejíard has a greater need for a similar defensive aid suite [DAS]. The SOV.17 includes the same Giod active protection system as the Nakíl, providing 360 degrees worth of defense.

The Giod is turret mounted and provides three hundred and sixty degree protection, using a laser warning receiver [LWR] for threat detection and transfer. The laser warning system was designed for instantaneous detection of laser rangefinders, designators and IR searchlights, indicating the direction and type of threat on a display screen provided for the tank commander. The Giod can fire smoke rounds, anti-personnel rounds or decoy rounds for up to seventy meters, the former lasting for around forty-five seconds and including a visual and multi-band screening agent. In cooperation, the system has an electro-optical jammer, sometimes referred to as ‘dazzlers’, which aims to jam the adversary’s semiautomatic command to line of sight [SACLOS], anti-tank guided missiles and laser rangefinders, as well as the infra-red targeting and rangefinders used by other anti-tank guided missiles, both newer and older. Giod can elevate and depreciate -5 to +25 degrees. The entire mechanism is activated by the laser threat receiver, and by pressing a button the tank commander [TC] activates Giod to automatically orient the turret in the direction of the threat. The ‘hard-kill’ part of Giod works in cooperation with the soft-kill sensor equipment, and has a reaction of time of ~.3 seconds, which outperforms the Soviet Arena. Furthermore, the Giod has a full three hundred and sixty degree area of protection, covering the dead area that would normally occupy the surface area rear of the turret. This section of Giod is intended to kill antitank grenades and anti-tank guided missiles, including those launched from aircraft, and it can locate any target approaching within one hundred meters of the tank, within the designated velocity band. After targeting the incoming missile and processing the data, the computer chooses the countermeasure, launching the munition, which detonates at ~1.9m to ~25m from the vehicle. .2 seconds later the system is ready to engage a new target. Giod fails to respond to false images of targets, such as small caliber projectiles, or slower flying objects, and it is day and night capable. Although there has been a concern for dismounted infantry, APS technicians claim that the danger to infantry men around the tank is less than one percent, and that the system works both to protect the tank and the infantry around it.

Giod also boasts of a hit-avoidance suite (HAS), which automatically detects, prioritizes and counters incoming projectiles. This includes a false target generation [FTG] active/passive decoy system, which is designed to emulate imaginary signatures to confuse incoming anti-tank guided missiles, and even smart rounds which are heavily sensor fused. That said, the HAS is simply an addition to the soft-kill abilities of Giod, and is considered one of the ‘leap-ahead’ technologies. The HAS is a fully integrated system of Giod and is one of the major technologies to increase the survivability of the vehicle in actual combat.

Further foward arc protection is provided by a series of four grenade launchers underneath the turret on either side of the front turret corners, working off the same systems as the Giod. Further foward arc and rear arc protection [not side arc] is provided by two AWISS systems on either side of the turret. Awiss takes advantage of a small Ka-band radar sensor, and can fire up to three counter-munitions in either direction. All four systems weigh about 800 kilograms collectively. Reaction time for Awiss is about four hundred milliseconds and the launchers can penetrate through ninety degrees in less than 140 milliseconds. The Awiss is not a home invention and is 'borrowed' from Diehl, a European defense company which designed Awiss back near 2003. Awiss, with ample software, was proved to be lethal, accurate and effecient, as well as cheap, all things that Kriegzimmer was interested in for the SOV.17 Ejíard.
