Sabre Tank Hunter
The Sabre Tank Hunter was a dedicated anti-tank hunter that was based on the Rhino chassis. It saw extensive use during the Great Crusade and the Horus Heresy. Like almost every single thing in the 41st Millennium, those jackasses with the cyber dildos forgot how to make these things making the Sabre a rarity within the Imperium, although how exactly the AdMech forgot something as basic as cutting a hole infront of the hull and sticking a gun through it is a mystery, even more when you realize this is basically a Vindicator with the dozer blade and demolisher cannon swapped out.
An updated version of the design (out of universe) has been released, titled the Sabre Strike Tank, offering a range of weapons from Volkites, Autocannon Battrey's, and Neutro Lasers, along with sponson mounted missile launchers and the usual pintle mounted fun.
Overview
It would seem that the Sabre would act as the middle child to the Cerberus Heavy Tank Destroyer, allowing to snipe enemy armored vehicles whilst using its smaller profile to hide within dense bushes or rocks. The Rhino itself was conceived to be easily modified to answer various specific needs like the Grimdark version of the Apple Iphone. Many Rhino variations have their origins during the end of the Great Crusade and the start of the Horus Heresy, when variations of existing vehicles to fulfill new roles became a necessity.
The Sabre was one of these modifications, seeing its first use during the earliest days of the Heresy, its design spurred by the need for heavier firepower. The Sabre was one of the type of Rhinos modified during the Heresy wars to mount heavier weapons, this type becoming known as "Tank Hunters" for the role they played during the Heresy. Besides the Sabre, various types of Tank Hunter were developed, each mounting different heavy weapons, such as missile launchers or lascannon. However, the Sabre was the most common form of Tank Hunter due to the ease in which a Rhino can be built.
As with other Tank Hunters, the Sabre has particularly thick frontal shielding to protect it from enemy fire. Its main weapon is a fixed forward-firing vanquisher cannon mounted in its front hull. A bolter is mounted alongside the much larger vanquisher cannon. The Sabre has no capacity to transport troops due to the weapons taking up so much space. In addition, the Sabre can be trade its vanquisher cannon with a powerful Laser Destroyer that is mounted on the front hull and is off-set to the left side of the vehicle to provide increased stability and reduce the overall silhouette of the vehicle for enemy targetting sensors. The tank can also be equipped with a Siege Shield, much like the Vindicator, which gives it forwards protection from enemy attack. The Sabre can also be outfitted with a dozerblade if it lacks a Siege Shield, extra armour plating, a Pintle-mounted Storm Bolter, a Hunter-Killer Missile Launcher, improved communications equipment, a searchlight, and smoke launchers.
