BDR-20 Armored Fighting Vehicle
http://img349.imageshack.us/img349/4290/bdr20acopy4ov.gif
Introduction
The BDR-20 AFV was designed to provide a vital nitch left almost completely left out of modern designing: combat reconnaissance and the support of the BMP-R IFV and T-115 MBT. The combat reconnaissance role usually entails aggressive seek-and-destroy missions, deep in enemy territory.
The BDR-20 is, simply put, superior to almost anything else in its category by outperforming them in speed, range, armor, and armament. It will continue to serve well into the next generation of tank design.

Armament
Main gun: The BDR-20 is fitted with the TK-120E/49 (2A73) 120mm 49-calibre smoothbore Electro-Thermal-Chemical gun. This gun was developed from the experimental 2A72 125mm smoothbore gun tested for the navy's warships, and is capable of a rate of fire as high as one round every three seconds. It employs a vertical rotary loading system, which occupies the loader's position within the tank. Its operation can be found in detail at the end of this description. The loader carries 8 ready-use rounds, with the remaining rounds being stored in vertical racks within the AFV.
Main gun ammunition types: APFSDS, HEAT, HEI-T, HE-FRAG, Smoke, ATGM (AT-21 Diamond (http://forums2.jolt.co.uk/showpost.php?p=7205007&postcount=10))

Secondary weapons: One coaxial 7.62mm PKTM MG with 14,000 rounds
7.62mm PKTM MG with 4,000 ready rounds
Optional weapons: none
Armour
The BDR-20 carries multi-layer composite-based armouring, which is built as follows:
1) Outer layer of 15mm Tungsten Carbide, designed to deform DU and Tungsten penetrators.
2) Layer of ceramics encased in plastic resins, approx. 30mm thick.
3) Layer of Type 22 composites, comprising titanium alloy rods in a horizontal lattice trilayer with coatings of Vectran spun plastic fibre, set within thermosetting plastics.
4) Layer of 20mm thermosetting foam plastic.
5) Layer of Type 22 composites.
6) Steel main body of AFV.
7) Synthetic, lead-based layer for use in elimination of neutron radiation.
Frontal armour equivalent RHA: 750mm
Side armour equivalent RHA: 550mm
Rear armour equivalent RHA: 150mm
Roof armour RHA equivalent: 175mm
Belly armour RHA equivalent: 100mm
Note that the fitment of Kontakt-VI ERA will boost each of these values by around 100mm.
Electronics
Fire-control system
The BDR-20’s main fire-control system for the main and secondary armament is the newer CTFC-11E IFCS, developed by the Colossus Section's Electronics Lab (CEL).
Navigation equipment
The BDR-20 carries the TINS system, but its main navigation aid is the TPS-2 tank GPS system. This has an accuracy of 0.4m.
Commander's Situation Computer
The BDR-20’s CSC is the CSC Mk.1 from CEL. CSC-1 is designed to allow the commander to both send and receive information from all other sources on the battlefield under any conditions, and has proven highly useful in exercises. It far surpasses the older and cruder method of radio reporting, in that now a picture can be used in place of speech, removing the inaccuracies therein.
CSC-1 is primarily intended for use by the unit commander to communicate data to his comrades in the theatre. It can both transmit to and receive from the CTFC-11E IFCS. In addition, it can be updated from compatible intelligence assets within its operating range. Data are transmitted via encrypted satellite link or in case this is too dangerous or not available digital radio transmitter. Updates from the GPS system can be delivered by either method at intervals of as little as two seconds (where intelligence must be immediate and accurate) to as much as 20 minutes.
Visual aids
The BDR-20 employs the A4M1 "Navada" thermal imagine sighting system, which is linked to the periscopes of both driver and gunner and to the tank's . The A4M1 introduces a further level of cohesion to the fire-control system with the introduction of the Wraith warning system. When this system is activated, the tank's six ImIR units for the TCM-20 system are used to detect any vehicle or heat-emitting object moving within range of detection but not within the field of view of ether turret crewman. Should these be recognized as hostile, the turret crew are alerted by a soft buzz and a small yellow arrow that appears on the screen, subscripted with the word "HOSTILE" and pointing towards the target. The CSC-1 is also updated with its position. This feature can be enabled at will, but allows the crew a greater degree of situational awareness than was previously possible.
Imaging Infra-red
The BDR-20 is equipped with the TKS-6 computer-controlled ImIR system, designed to allow early detection of incoming ATGMs. The TKS-6 is controlled by the main fire-control computer, and its omnidirectional detectors scan constantly for the characteristic backblast and flame of an ATGM launch. Upon detection, the main FCS alerts the crew and deploys all available countermeasures.
Countermeasures systems
The BDR-20 is equipped with the TEC-3 countermeasures suite, which integrates the Shtora-1 optronic jamming system (for use against ATGM lasers, IR seekers and laser rangefinders) with the CrossLoop radio jamming array (for use against ATGM radars and enemy radio).
CrossLoop has a range against most modern radio systems of around 10 Km and can be programmed to track specific code sequences within transmissions.
Propulstion systems
Engine
The BDR-20 is powered by an updated version of the DSO-1400 multi-fuel Deltic-pattern diesel engine in the T-94B and T-95M, the same engine in the T-115 MBT. This being used to ease logistics and repair. The DSO-1400A is rated at 1,992 BHp and has eighteen cylinders arranged in the "Deltic" configuration of 10.7L capacity.
Transmission
The BDR-20’s main transmission is the TTS-45 gearbox. It is a planetary gearbox, with seven forward and three reverse speeds. TTS-45 was noted during trials for high reliability even when subjected to the harshest performance tests in terms of longevity, treatment and climate.
Miscellaneous
The BDR-20 is fully NBC-sealed, employing filters and an overpressure system to keep contaminants out of the vehicle, and the infantry may fire their personal firearms from the vehicle without compromising its NBC integrity providing appropriate sealing measures are taken.
The engine is surrounded by a small airspace and a layer of foam plastic to help in dissipating heat. The exhaust pipes are wide and small, and have internal IR mixer boxes. The engine bay is also designed to accommodate larger engines when they become available.
The vehicle's major parts are designed for easy removal and replacement, and it is provided with a full set of tools for any operation including stripping out the engine and transmission. It also carries spare parts for all of the major failure-prone systems within it.
To prevent a single mine from taking out the entire vehicle, it is equipped with run-flat, tires and can run on 6 wheels if necessary.
The BDR-20 is equipped with air-conditioning systems for both the crew and the engine. It is also equipped with a full backup starting system in case of primary starter failure.
