The Harma is a family of tracked combat vehicles designed in 1995 by the Belfrasian Military Systems (BMS) for service with the Belfrasian Army. Originally developed to replace the older series of armoured perseonnel carriers and infantry fighting vehicles deployed by the Army from the 1960s to the 1980s, the Harma has been expanded further to include a wide range of roles.
Best described as a multi-role infantry fighting vehicle, the Harma comes in variants such as the standard Infantry Fighting Vehicle, Armoured Personnel Carrier that focuses on carrying more personnel over fighting capabilities, self propelled howitzer versions, air defence versions, and variants for supporting armoured units. The vehicle entered service in the late 1990s and the composition of several vital components, such the armour, have remained classified. The Belfrasian Army, following trials, noted that the vehicle's armour was rated to vitally improve survivability of function and personnel against small arms and anti-armour munitions.
BMS stated during the unveiling that the Harma was developed to work in tandem with heavier armoured vehicles, such as the BMS Parmenio MBT which as undergoing trials at the same time. The Army has noted the versatility of the Harma when used in a combined arms warfare scenario, such as a tank platoon navigating through a city. In open areas, the rapid and rugged methods of movement the Harma can perform to cross rough terrain has in exercises shown that troops can be deployed to support larger operations or as the figurative 'main thrust' of an operation.
History
Design
When the request for a new armoured vehicle family came in, the requirements for different variants using a common frame resulted in major differences in armour, engine and electrical systems. The family has been upgraded several times in it's life, featuring increasing more powerful engines, weapons, and survivability methods. Most recently, the armoured vehicle family has been updated to contain an automated defence suite that categorizes potential threats and, in automatic mode, can fire countermeasures against incoming threats or to counter potential threats such as anti-tank equipped infantry or armoured vehicles.
The default model of the vehicle utilizes a Majestic DSS55 engine to provide a top speed of 43 MPH on road and 31 MPH off-road with governing systems that can be deactivated for a temporary sprint capacity of as much as five to ten miles an hour for periods of up to three to five minutes as needed. The DSS55 is an improvement upon the original DSS20 engine used in 1999-2005 with a new hybrid-electric propulsion system that has an attached battery pack that is recharged during movement and can assist movement of the armoured vehicle or to provide non-engine provided movement for the turret and operation of onboard equipment. Tests have proven that this allows reconnaissance versions to cut it's engine and operate all electrical systems in a quiet environment for periods of time, although the exact amount of time remains classified.
The suspension system of the Harma was upgraded in 2014 with an active dampening system that analyzes upcoming terrain and current speed to adjust the suspension at particular points to stabilize the vehicle as much as possible. The system has been perfected after a year of trialing has proven to increase speeds off-road to allow it to outrun some other types of armoured vehicles and to drastically reduce the pitch the vessel experiences when rapidly accelerating or decelerating. The system has, additionally, provided greater maneuverability and stability on both rugged terrain and to provide a much more stable environment for the gunner during firing when moving. The system has proven to be successful enough to prompt changes
During the development of the Harma armoured vehicle, BMS provided a classified armour system that, whent ested, proved for survivability against 14.5mm armour-piercing rounds utilized in weapons such as the Rodarian {{wpl|Denel NTW-20|HSRA-80]]. Whilst some variants since the development have standard protection against 30mm Armour-piercing fin-stabilized discarding-sabot (APFSDS), others are capable of mounting MEXAS, a modular strap-on armour system that can give variants with thinner armour the same protection against 30mm APFSDS rounds. The same armour system is also intended to provide protection against ambush devices such as improvised explosive devices, explosively-formed penetrators and various kinds of anti-armour or armour-piercing munitions. The interior of the vehicle is lined with pieces of kevlar, designed as a pre-fractured network within a contained lining to slow and stop shrapnel that penetrates all layers of armour in order to reduce or prevent injury to personnel. Cage armour can also be fitted to the Harma, even on top of the MEXAS armour system, to provide effective protection against anti-tank warheads utilizing a tandem or shaped charge warhead. Armour mounted under the vehicle along with a uniquely shaped underside provide protection against anti-tank mines.
Answering requests by the Belfrasian Army for survivability against Nuclear, Biological and Chemical (NBC) attacks against military units in the event of war, the Harma comes natively with an advanced NBC filtration unit to strictly control the flow of air in and out of the vehicle. chemical and radiological detection systems also exist although more advanced systems are available on reconnaissance versions.
The Harma is equipped with dual-sided, directional vents that can be redirected by the commander to drastically reduce the heat image emitted. This system also exists with heat-absorbing filters that provide a level of temporary protection against thermal imaging or infrared cameras and improved protection against heat seeking munitions when used in combination with the vehicles small array of chaff. Small launchers exist that would provide a 360 degree angle of protection against heat-seeking munitions, which also compliments smoke launchers on the vehicle.
Methods for offensive operations by the basic IFV model of the Harma include the usage of a two-man turret armed with a 40mm caliber main gun with a coaxial 7.62 mm machine gun. Two remote pintles exist for weapons to be used by both the gunner and commander for weapons such as general purpose machine guns, heavy machine guns, or grenade launchers. The basic turret also features two clusters of three launchers on each side of the turret for smoke dispersion methods. The commanders pintle comes with a remotely operated camera array that uses the same daytime/thermal imaging system along with a new generation of image intensification and identification software to identify personnel and types of vehicles encountered in the field.
Recent developments have begun into thermoelectric plates that would provide an infrared camouflage. This, in theory, will allow a vehicle to disguise itself as other objects such as civilian vehicles, trees, nor to make itself invisible entirely to infrared cameras. Tests are still being conducted as of early 2016 to determine the abilities to counter heat-seeking munitions.
