Object 165
-
-
The Object 165 — also known as the T62A — was a cold war era Soviet tank. (I’ll finish the history info later)
-
For the technical aspect of the model. It has the exact same hull as the Object 150, so it retains all features the previous model had (full independent suspension, an acute angle between upper and lower front plates, and good structural integrity). The turret is new, and features an elevating and depressing gun. Fundamentally, it uses the same building techniques as my old T55 turret so it inherits the same level of integrity.
-
I built this during the New Years holiday period this year, but postponned posting (I have plans for other things too 😉, but don’t get your hopes up!) hence the delay.

Hope you all like the blue, some photo quality was sacrificed for that.

VTCD-3 (30) with Variable Track System Active

[Part 2]

Perhaps the most notable innovation in UGV development to come out of the Preservationist Coalition's OPSCOM Development Bureau was the Variable Track System (VTS), which was first tested and fielded on the VTCD-3 (30) Variable Tracked Combat Drone (30mm).

The VTS was intended to act as a rough simulation of "legs" for the drone, which would theoretically allow it to more effectively un-ditch or otherwise dislodge itself from situations in which it may be "stuck" or bogged-down. To this end, of the drone's tracks are mounted on independent track pods on each side of the core block, and these track pods can both spread outwards as well as pivot up and down. The latter function can also raise the core block up from the horizontal, thereby enhancing the turret's vertical coverage so it can fire at targets at a much higher elevation than the VTCD-3 itself.

The first production batch of VTCD-3's reached the frontlines in time for Operation Hornet's Nest, where they made their combat debut against Dominion's North Guards Mechanized Army Group. The VTCD-3 proved to be an effective "armored car destroyer", a low-risk counter to Dominion's roving platoons of heavy Razvedchik armored cars, but its lack of dedicated anti-tank weaponry hampered its ability to combat any opposing Udarnik main battle tanks.

Despite the innovative aspect of the VTS implemented within the VTCD-3, the drone's lack of advanced protection barred it from membership in the Arms Consolidation and Standardization Program (ACSP) series of state-of-the-art combat vehicles.

Nevertheless, the VTCD-3 proved its worth in the field, and it would continue to see service until the end of the Central Campaign. It would also gradually supplant its predecessor, the TCD-2 Medium Tracked Combat Drone, in order to conserve the latter's Schmalpanzer 10t chassis for conversion into the successful Jagdpanzer 15t line of tank destroyers.

Overall, the VTCD-3 was an effective drone that provided greater armor and offensive capability than the average MBTk-1 could within the same weight class, while also preserving human resources by virtue of it being a UGV.

VTCD-3 (30) Variable Tracked Combat Drone (30mm)

[Part 1]

With the Preservationist Coalition spearheading the development of unmanned ground vehicles (UGV's) during their conflict with the invading forces of Dominion, many advancements in drone development came out of the OPSCOM Development Bureau throughout the Central Campaign.

One landmark design which broke the mold for traditional UGV's was the VTCD-3 (30) Variable Tracked Combat Drone (30mm). This was named after its unique feature, the Variable Track System (VTS), which will be covered in detail in [Part 2].

Weighing in at just under 8 tonnes, the VTCD-3 is fitted with a standard MBTk-1 petrol engine repurposed as a gas generator to recharge the battery. The battery itself is housed in the rear section of the core block, and it powers the drone's radio, turret, onboard computer, and electric motors necessary to drive the tracks and manipulate the VTS. This battery is rated for 8 hours of active use on a full charge, and up to 18 hours on standby/surveillance.

The core block is well-armored for its size, though it relies on classic rolled homogeneous steel for protection, foregoing composite or reactive solutions to reduce costs. With 50mm of frontal armor (sloped back at 45 degrees for over 70mm effective thickness) and 40mm sides and rear, the VTCD-3 can resist 20mm APDS rounds frontally and is proof against heavy machine gun fire all-around.

The VTCD-3's turret is essentially a dense cluster of weapons and sensors. For armament, it features a drum-fed Forefront Armored Systems (FAS) 30mm autocannon with alternating APFSDS/HE rounds, a coaxial 12.7mm Mk. III heavy machine gun, and a pair of small smoke grenade launchers. The main camera is offset to the lower left of the 30mm barrel, and the targeting computer is fitted above the gun assembly along with a large high-beam spotlight.

As with the engine, the VTCD-3's running gear is also borrowed from the venerable MBTk-1 tankette, albeit truncated with the exclusion of the idler wheel and one return roller. With it, the drone can reach a top speed of 50 km/h, and up to around 40 km/h cross-country at a range of up to 3km from a drone control center.

MG-001-B (D) Mobile Gun 001 B-Type (Desert Ver.)

[The Aftershock]

#aftershockworld

-----

In the autumn of 2117, what began as territorial disputes quickly escalated into large-scale open conflict between Steel Rain and the Terran Accord in the Asian Theater.

The subsequent opening of the Central Asian and Middle Eastern Fronts meant that Steel Rain's forces would find themselves engaged in combat within arid climate zones far removed from the largely subarctic regions that their hardware was originally designed for.

Appearing in mid-summer 2118, the MG-001-B (D) was to serve as the successor to the MG-001-A as SR's most basic autonomous infantry support unit, incorporating harsh lessons learned in the opening months of their war with the Terrans.

First, the B-Type's armor layout was streamlined and reinforced with additional composite armor add-on plates. Minor spaced armor shielding was also added to protect the hip joints from the front and rear. The lower legs were simplified to ease production, and the feet were redesigned to feature toe articulation for more smooth running.

Supplementing the original 30x165mm main autocannon was a new coaxial internally-fed 7.62x54mm machine gun opposite the small radome and extended radio antenna.

Unique to the Desert Version of the B-Type are the special rubber gaskets added to some of the joints in an effort to prevent particles from entering the components and causing unnecessary wear and tear; a useful addition given the frequency of dust and sandstorms on the arid fronts SR was engaged in.

Further field modifications include an appliqué armored cover for the main camera as well as the mounting of four 30mm smoke dischargers to each upper leg to counteract ATGM targeting.

Overall, the MG-001-B (D) is considered a far superior model to the A-Type it replaced, being more mechanically reliable and easy to maintain in the warmer, dryer climes of the Central Asian and Middle Eastern Fronts.

Later in the early 2120's, Steel Rain would deploy the same desert-use B-Types in the Western Hemisphere upon encountering the Phoenicians during SR's expansion into the Great Basin Front of the North American Theater.

Anthology Series Aircraft Pilots

[Anthology Series]

-----

This post is another follow-up to that of the ACV-CAST Hatchetfish Armored Attack Helicopter, this time showcasing the new aerial pilot uniform I came up with. I have made three pilots with identical uniforms but different faces, all of which can be seen in the first and second images.

The reason I specifically referred to these as "aircraft pilots" is because I wanted to distinguish them from walker pilots and other mech crewmen, which typically operate on the ground. The aerial suits are partially-pressurized (as needed for airmen) and designed specifically for flight at varying altitudes. The Hatchetfish seats only one pilot, but I made spares to crew any future aircraft I may design.

In the third and fourth images, you can see ground mech crewmen operating the GCW-FST Notornis, who have no oxygen masks and overall don a more simple "soldier-like" uniform, rather than a pilot suit.

-----

The parts used for the aircraft pilot uniform are listed below, from top down:

Part 41805 -
"Minifigure, Visor Flight Helmet" (in Trans-Light Blue)

Part 93560 - 
"Minifigure, Headgear Helmet Sports/Flight" (in Light Bluish Grey)

Part 39796 - 
"Minifigure Breathing Apparatus, Aviator Oxygen Mask" (in Light Bluish Grey)

Part 973pb1785c01 - 
"Torso SW AT-AT Driver with Sand Blue Jumpsuit, Bib with Breathing Apparatus and Pipes on Back Pattern / Sand Blue Arms / Light Bluish Gray Hands"

Part 970c00pb0700 -
"Hips and Legs with Sand Blue Straps, Black Belt, and Dark Bluish Gray Knee Pads Pattern"

-----

I am actually quite happy with how this outfit turned out, as I mostly threw it together from the parts a single Bricklink store I frequent had in stock, but it looks fairly cohesive with its color distribution and matches well with the Hatchetfish's color scheme. Not to mention the fact that the "box" on the AT-AT driver torso lines up well with the oxygen mask's breathing hose!

In any case, this should conclude my Hatchetfish content, at least for the time being. For my next post I intend to return to the #aftershockworld collab along with my favorite color to build in: Tan! I hope you'll look forward to it!

ACV-CAST Hatchetfish Armored Attack Helicopter

[Anthology Series]

-----

The "Air Combat Vehicle - Close Air Support Type" is a further development of the ACW-TR-1 Aethon tiltrotor walker, created with the objective of significantly reducing the costs of the predecessor model while retaining as much of its operational capability as possible.

To this end, the ACV-CAST drops the tiltrotors and walker leg mechanisms in favor of a single primary rotor + tail rotor configuration, converting it into a conventional helicopter. Because of the radical restructuring of the hull required to accommodate this new arrangement, the ACV-CAST has effectively become an entirely new vehicle, with only the original cockpit block being carried forward from the Aethon.

This new helicopter would ultimately bear the name "Hatchetfish" due to its silhouette: it features a convex, rounded hull with a pronounced bulge on the lower side, which combined with the large vertical stabilizer fin at the end of the tail boom emulates the image of freshwater hatchetfishes from the family Gasteropelecidae. Fittingly, these fish are noted for their ability to take flight, proving to be rather mischievous escape artists when kept in captivity.

Fitted with a lightweight composite armor coating backed by carbon fiber, the Hatchetfish can withstand 12.7mm heavy machine gun fire from all directions. Critical areas such as the frontal cockpit block and twin turboshaft engine housings are also proof against 25mm HEI rounds.

For armament, the Hatchetfish features modular weapons packages for each wing. The standard complement aims for versatility with its inclusion of two nine-tube rocket pods, a drum-fed 20mm autocannon, and a four-tube missile pod equipped with a pair each of air-to-air and air-to-ground missiles, supplementing the default nose-mounted 5.56mm light machine gun.

Visibility for the pilot is considered sufficient despite the lack of a windshield due to the placement of various advanced sensors around the hull. Low airspeed sensors parallel to the wings are fitted to the sides of the engine housings, which assist with weapons targeting alongside the dedicated coaxial weapons cameras.

CRA-GC/90HV Ballista-class TD (CRA Service with Crew)

The Ballista-class tank destroyer was built on the CRA-MT 24-tonne medium tank chassis, which served as the basis for all of the tracked armored fighting vehicles in service with the Cadaubrian Royal Army (CRA).

The standardized chassis featured welded armor panels, with a 100mm-thick lower frontal glacis at sloped 30 degrees from the vertical (~115mm effective thickness) and a 60mm upper frontal glacis sloped at 60 degrees (120mm effective). The 40mm side and 30mm rear plates were made vertical to ease production.

The CRA-GC ("GC" for "Gun Carriage") variant of the CRA-MT chassis was modified from the basic design by shifting the engine from the rear to the front-left section, adjacent to the driver's position, thus providing room for a gun mount atop the rear deck with ammunition storage below. The total mass of the Ballista was 28 tonnes after the addition of the open turret, which featured a large angular gun shield with an 80mm frontal slope at 50 degrees (~120mm effective) as well as 40mm vertical sides. Altogether, the armor was proof against 30mm APFSDS rounds frontally, and heavy machine gun fire on all other sides.

The armored hatch on the rear protects the ammo racks, which can hold 26 rounds within the hull. Combined with the two shells on the turret's "ready rack", a total of 28 rounds can be carried, typically a mix of 11 APFSDS and 17 HE rounds for the Ballista's 90mm High-Velocity (90HV) gun. The APFSDS round could penetrate 410mm of steel at 2,000 meters; simply devastating against armor.

However, due to the nature of the civil war that the CRA found itself engaged in, hostile tanks were few and far between. This forced the Ballistae into use as direct fire support weapons against fortifications and soft targets, making HE the preferred shell type. While the 90mm HE round was sufficient for such duties, and the 90mm HV gun's relatively generous +25/-10 degrees of elevation/depression allowed for a degree of flexibility in the targets it could engage, the exposed positions for the gun crew were a significant detriment to the vehicle's effectiveness when used in offensive operations.

ML-IRG-AT/125 Buster Man-Portable Missile Launcher

[The Aftershock]

-----

Derived from pre-WWIII hand-held anti-tank weapons, the ML-IRG-AT/125 Buster was introduced to the Terran Accord's arsenal in late 2109. Intended as a lightweight and easily-deployed armor-defeating weapon, it played a key role in the Accord's early years as a supplement to their then-nascent armored fleet by providing the Frontline Forces infantry with the power to knock out most early Aftershock-era hardware. As such, the Buster served as a stopgap which provided the Terrans enough time to develop the heavier armored vehicles needed to expand their fleet into the imposing force that would become the Accord's hallmark in the African and Asian Theaters.

Following standard TA nomenclature, the designation is as follows:

"ML" = "Missile Launcher"
"IRG" = "Infrared Guided"
"AT" = "Anti-Tank"
"125" = "125mm Caliber"

It should be noted that the common name "Buster" applies to the launcher itself, not the missiles fired from it (which are shared across most of the Accord's launchers). The Buster is a "fire-and-forget" launcher using an infrared-guided lock-on system that allows the user to immediately take cover post-launch. Simple to use, the Buster can toggle between top-attack and direct-fire modes.

Two types of ammunition are commonly available for the Buster: tandem-charge High-Explosive Anti-Tank (HEAT) and General-Purpose Warhead (GPWH). The former is identified by its yellow marking and standoff spike, while the latter has a red band and a characteristic bulb designed to maximize fragmentation upon detonation.

Despite appearances, homing missile systems such as the Buster have a fairly high level of complexity that makes them less cost-effective than traditional cannon-based artillery. For this reason, by the mid-2110's the Accord relegates ATGM systems to only supplemental roles. Even so, the Buster's effectiveness has made it popular among the TAFF, and has cemented its position as a mainstay in the Accord's arsenal for the foreseeable future.

Outrider DT Engine Overheated During Trials

-----

The crew of a pre-production model Outrider DT attempts to troubleshoot an overheated engine during trials. As the smoke rises from under the open engine hatch, a crew member realizes that a jammed cooling fan is the culprit, though the underlying source of the issue was likely a malfunction or blockage within the rear-mounted sand filters for the engine air intakes.

-----

The FAS-2DT (20) Outrider Desert-Tropical Type (20mm) was a high-speed light tank intended for reconnaissance and rapid-response duties within the tropics of the southern continent. Introduced in the closing stages of the continental war, this tropicalized variant was developed and built solely by Kifaru Machining (KM). This was because the original designer of the FAS-2 Outrider chassis itself, Forefront Armored Systems (FAS), was struggling to hold the line against Dominion's North Guards Mechanized Army Group around the Pygmy Peaks at the time.

Naturally, FAS could not spare any personnel to advise on the project, so the only assistance KM had for producing this tank would be some documentation they managed to acquire from OPSCOM, the Preservationist Coalition general headquarters. Since the original Outrider was built for operating in the cooler temperate climate of the Northern Front on the central continent, KM encountered reliability issues when attempting to meld the chassis and engine with their trademark sand filters and air intake design.

Because of the Outrider's high top speeds (95 km/h on roads, up to 65km/h cross-country), the light tank's high-output engine frequently overheated during trials due to insufficient cooling. Shifting the air intakes to the rear and applying KM's sand filters ended up restricting the airflow too greatly for the original radiator and cooling fans to handle. These were later replaced with new KM-designed components to rectify this issue for the mass-production models. Furthermore, a togglable rev limiter was installed to reduce the engine output and keep it well within safe operating parameters, though this would reduce the top speed by 15% when active (~80 km/h on roads, ~55 km/h cross-country).

75mm Lightweight Cannon (Towed Variant, KM Service)

The 75mm Lightweight Cannon, simply referred to as the "75L gun", has a rich history that began in the earlier stages of the continental war between the Preservationist Coalition and the Dominion invaders.

In the immediate aftermath of the Breakout of Centerpol, the Coalition members found themselves severely depleted of their pre-war equipment reserves which were lost in the heavy fighting against Dominion's encircling forces. It was at this point that the Arms Consolidation and Standardization Program (ACSP) was enacted, in order to streamline the production of weapons and vehicles between all Coalition members so that frontline losses could be quickly replaced in the following years.

Perhaps one of the most significant contributions made to the ACSP was the development of the 75mm Lightweight Cannon, provided by the Ordnance Office at Mechanized Security Solutions (MSS). The 75L gun was one of many pieces of artillery with origins from this office and would see service on all fronts during the Central Campaign.

The 75L gun was designed from the onset to be compact, lightweight, simple, and cost-efficient. It had only a moderate overall length thanks to its cut-down barrel and breech assembly. To minimize volume, the hydraulic recoil cylinders were placed in parallel flanking the barrel, mounted in an elliptical housing ahead of the trunnions with a small armored mantlet. Because of its lightweight design, the 75L gun had a lower-pressure chamber and thus could fire APFSDS shells with only 200mm of steel penetration at 2,000 meters, inferior to the pre-war standard of 260mm+ at the same range (yet still able to defeat the frontal armor of Dominion's P-30B/100 Udarnik tanks at ranges below 1,200 meters).

The 75L gun would end up seeing heavy use by all Coalition members throughout the remainder of the war, being mounted on a variety of chassis. The cheapest option was a simple towed carriage with a split trail and a small gun shield resistant only to small arms fire. Kifaru Machining (KM) would later import many of these towed guns and paint them in their characteristic two-tone desert camouflage.
