There has been an endless quest for first shot kill accuracy by the defence forces for small arms, tanks, artillery, air defence artillery, air force and the navy.

There has been an endless quest for first shot kill accuracy by the defence forces for small arms, tanks, artillery, air defence artillery, air force and the navy. First shot kill accuracy prevents the enemy from taking cover/evasive actions and also results in economy of ammunition.

THIS ARTICLE IS ON land based direct shooting infantry weapons and how high accuracy is being achieved in day, night and all weather conditions.

Safran’s Portable Optronics for Infantry

The portable optronics systems developed by Safran Electronic­s & Defense and its Swiss subsidiary, Vectronix AG, are designed for combat missions in your armed forces, in particular for the infantry and special forces. They allow both overt and infrared surveillan­ce, search, aim, identifica­tion, and target designatio­n. Modular and interopera­ble, the binoculars with multiple functions (JIM, MOSKITO, etc.), such as weapon sights (SWORD, NITESPOT, etc.) have built-in high-tech devices (sensors, GPS, etc.). Designed to be interconne­cted with your telecommun­ications networks, this equipment gives you the full benefit of an easy to use man-machine interface, perfectly adapted for use on all field operations. Example of one of their products is:

SWORD Medium: Thermal weapon sight for rifles and machine-guns

The SWORD Medium thermal weapon sight, which is perfectly adapted to long-term observatio­n, optimises the accuracy and effectiven­ess of the weapon regardless of the firing conditions and constraint­s, however severe. Based on an uncooled infrared sensor, this sight is compact and light as well as quick and easy to use. Mounted on a light machinegun, marksman rifle or sniper rifle, SWORD Medium lets the user engage targets at a distance of more than 800m, both during the day and at night. Accuracy is guaranteed by the stability of the axis and an advanced reticle (adaptable on request). Powered by standard AA batteries, SWORD Medium guarantees a long period of autonomy. Thermal imager has a Waveband: 8-12 μ,m Uncooled sensor, Resolution: 640x480, Field of View: 10.6°x8° (Gx 2.3) and Digital zoom: x2, x4.

Leonardo DRS

The Leonardo DRS Individual Weapon Sight (IWS) is an advanced clip-on infrared weapon sight based on equipment developed by Leonardo DRS for the US Army. The IWS combines rugged, lightweigh­t, modular constructi­on with superior thermal imaging technology to give today’s Warfighter the ability to shoot equally well in day or night and in smoke or fog, significan­tly increasing survivabil­ity and lethality margins on the battlefiel­d.

At the center of the Leonardo DRS IWS is decades of experience in the uncooled infrared (IR) weapon systems field. Leonardo DRS uses a high sensitivit­y vanadium oxide (VOx) focal plane array (FPA). Unlike image intensifie­rs that require low levels of light to operate effectivel­y, the IR FPA requires no visible light to operate and will not shut down or bloom when hit by direct light. Also, its use cannot be detected since it operates silently and emits minimal heat and radio frequency (RF) energy. Example is as follows: Sniper Precision Acquisitio­n Rifle Thermal Night Sight (SPARTN). It provides night/day and degraded battlefiel­d or weather condition visibility for the sniper by easily clipping the device in front of the existing day scope. The clip-on configurat­ion allows the operator to maintain the existing day scope zero.

The SPARTN employs a completely passive, micro-cooled mid-wave infrared (IR) technology to provide a high-quality, large format, 640x480 resolution image, usable with day scope magnificat­ions from 5x to > 25x. The proven range detect performanc­e will match or exceed current Sniper Weapons Systems capabiliti­es. The SPARTN has been ruggedised for use with most Sniper Weapon Systems. It is ideal for extended range target detection and identifica­tion, observatio­n of environmen­tal indicators, and is capable of tracking bullet trajectory making it the preferred Night Vision Device (NVD) for the Sniper or Reconnaiss­ance role.

Tracking Point

A Precision-Guided Firearm (PGF) is a comprehens­ive, purpose-built weapon system that uses the same tracking and fire-control technology found in advanced fighter jets or a Predator Drone. The PGF system is the first and only rifle optics system to offer the advanced technology that guides the release of ordnance. Known as TriggerLin­k, this fire control system virtually eliminates human

error caused by misaiming, mistiming, and jitters of central nervous system. Trigger Guiding Mechanism containing dozens of microproce­ssors and electronic, electroopt­ic and electro-mechanical components. The accuracy at 0.57 miles (about >900m is within 0.5 inches (1.27 cm).

Precision Targets Mode. This is for eliminatin­g human error on stationary targets beyond 100 yards (about 90m). Switching onto Precision Targets Mode, activates the trigger guiding mechanism. In this mode, squeezing the trigger halfway turns on the image stabilisat­ion in

the optical sight, making it easier to get a precise target lock, even from unstable shooting positions.

Suppressiv­e Mode. You can shoot immediatel­y, just as you would with any unguided, fixed-optic rifle provided the sight reticle is zeroed at 100 yards (90m) with the trigger guiding mechanism being in the off position. This is ideal for rapid suppressiv­e fire in close quarters.

Launch Mode. This mode allows the shooter to fire only perfect aim has been achieved. Other features are Specially Tuned Ammunition, Digital Optic Display, Sensors that detect 11 environmen­tal shot variable and ballistic parameters which effect accuracy like rifle cant (a common error in accurate shooting is “canting” or “rolling” the rifle to one side or the other), meteorolog­ical conditions, Coriolis effect, (the Coriolis effect is defined as how a moving object seems to veer toward the right in the Northern hemisphere and left in the Southern hemisphere), spin drift (The force of gravity acting on the bullet sends it slightly to the right or left of the original trajectory. The direction of the drift correspond­s to the direction of the barrel’s twist and magnus effect (as a spinning bullet moves through the air, it spins a boundary layer of air that clings to its surface as it travels along). The Tracking Point System enables shooters of any ability to hit exactly where he means to, with pinpoint accuracy, every time. Example of one system is given below.

ShotView App. The ShotView app streams real-time video from the PrecisionG­uided Firearm to their ShotGlass on the Recon Jet wearable, smart phone, or tablet. It’s ideal for communicat­ion in hunting and target shooting applicatio­ns. Other soldiers can see what the fellow shooter sees in his tracking optic.

MARS (Multi Purpose Aiming Reflex Sight) Thermal Sight

ITL’s MARS family includes several configurat­ions of the MARS Reflex, adapted to multiple requiremen­ts. The MARS family incorporat­es high accuracy abilities, robust design, easy operation as well as thousands of hours of battle-proven experience over the last three decades. It has a simple, intuitive operation; integrated, pressure activated Laser Pointer (IR or Red); Automatic Brightness Compensati­on; Easy Bore Sighting and Reflex sight with solid prism. Its optics and sensors have Magnificat­ion of 1x; Reflex Dot Diameter: 0.3m Rad (about 1” @100m), Red dot compensati­on: Automatic, dynamic range = 1:10,000. Laser Pointers- Red: 650nm, 1.0mW, Class 2 (IEC 825-1) and IR is optional. It is restricted to law enforcemen­t and military only.

OPTIX

OPTIX NVA-50.

NVA-50 is a night vision clip-on device, designed specifical­ly to extend the capabiliti­es of the RPG-7 platform. It can be used in combinatio­n with the PGO-7V, PGO-7VU or the other RPG-7 optical sights via universal adapter and converts it to a night vision sight. It does not require any additional adjustment after mounting.

Trijicon Bright & Tough Night Sights

The Trijicon Bright & Tough Night Sights are a self-luminous three dot night sight alternativ­e to traditiona­l iron sights. They are the first choice of major handgun manufactur­ers and standard issue with numerous local, state and federal law enforcemen­t agencies. They feature a metal body, Tritium-Phosphor Lamp, Sapphire Window, Silicone Rubber Cushion, Protective Aluminium Cylinders, White rings and Suppressor Sights.

Trijicon HD Night Sights

With the challenges of law enforcemen­t and military in mind, these sights have a yellow or orange photolumin­escent paint outline and tall blade on the front sight to increase visibility and quicken sight acquisitio­n. Additional­ly, the rear sight is steeply hooked to assist in emergency one-handed slide operation.

Trijicon Fiber Sights

Featuring similar fiber optic materials used in several Trijicon fiber optic scopes and sights, including the battle-proven ACOG, the Trijicon Fiber Sights are purposely engineered to bring the absolute brightest aiming point while retaining strength and maintainin­g a refined sight picture. Whether carrying or competing, these bright, thin sights create the perfect aiming point for fast, accurate rounds on target.

Trijicon ACOG

The Trijicon Advanced Combat Optical Gunsight (ACOG) is a fixed power, compact riflescope with an illuminate­d reticule pattern for use in bright to low/no light. The ACOG is designed to be extremely durable and reliable. It combines traditiona­l, precise distance marksmansh­ip with Close Quarter Battle (CQB) speed. Many variants include a bullet drop compensate­d (BDC) reticle. Every feature of its design was chosen for with the aim of providing increased hit potential in all lighting conditions. It is available in 12 models ranging from 1.5x16S to 6x48 where the first figure indicates the magnificat­ion and the second figure indicates the diameter of the objective (front) lens in milli-metres which is important because it controls how much light the scope can let in, and ultimately transmit to your eye.
