Designed due to a requirement by the IPF Command that the Planetary Forces would face hostile, oftentimes non-human, super-heavy armour on the battlefield - the Ogre was built to carry the most powerful ground-based armaments in service, along with the heaviest and most capable protection systems. During the transition to the Imperial Era in 4404 A.D, the former UAS Ground Forces' inventory was rapidly converted and entered service with the newly formed Imperial Planetary Forces. The existing Heavy Tank, the relatively novel grav-gyro powered HPAV-2205 was considered for mass production but ultimately cancelled in favour of a new design to accommodate emerging technology advancements enabled by the Directorship.

The Ogre takes the 'Heavy Assault Tank' concept to the extreme, utilising gravimetric gyro propulsion to offset the otherwise immense mass of the vehicle. Despite this, the vehicle's design doesn't permit high mobility; instead focusing on providing a high-endurance platform to mount the IPF's new MA/FIMD-200 Assault Gun, which had just entered serial production when the Ogre was first tested in 4405 A.D. The FIMD-200 is a 200MM long-barrel Kinetic Mass Driver with a slightly smaller diameter to the 205 MM gun on the HPAV, but a much longer projectile and almost twice the chamber pressure. This gun was designed in tandem with the new platform since the firing assembly was simply too large to mount to existing HPAV hulls.

The intention of this weapon was to be able to counter any heavily armoured (considered 'super-heavy') threats that the smaller, more mobility focused vehicles like the Griffon Light Tank, simply couldn't carry weapons powerful enough for. The concept called for these 'centrepiece' vehicles to form the spearhead in armoured assault divisions and confront enemy forces directly, using overwhelming firepower to break their lines and neutralise heavy threats in situations where orbital or atmospheric support was unavailable.

The Ogre is equipped with front and side composite arrays consisting of high density Adaptive Armour inserts layered between LMNPA (Low-Metallic Nanopolymer Alloy) sheets. The adaptive armour is able to change atomic structure depending on the threat (threat response on impact, or pre-modified by the Battlefield Awareness System). These composite arrays are up to two meters thick on the frontal arch, making the Ogre incredibly resistant to enemy fire. Additionally, add-on DAP units are installed by standard. The Ogre also uses a five-point CVPCAPS 3-layer Threat Response System (as used on essentially every IPF armoured vehicle, however, only the Ogre has a 5-point system).

In addition to fulfilling the requirement for a Heavy Assault Tank, the Ogre was also designed to function as Self-Propelled Indirect-Fire Artillery (SPIFA) and as such the design allows for extreme elevation (up to 50 degrees vertical) of the main armament; which was also designed for both high and super-low velocity operation allowing for the exploitation of heavy-mass projectiles with ballistic curves in medium or high gravity environments. Furthermore, this elevation also allows the Ogre to use the FIMD-200 in high velocity operation against atmospheric threats such as dropships or even small warships such as Corvettes in low orbit.

The Ogre's size permits additional armaments; the vehicle uses a modified version of the Minotaur IFV Turret as a secondary armament atop the main turret. This variant uses a single semi-automatic FIMD-75 (75MM) gun with a FIMD-20 (20MM) PDS system on top of that. In place of the second FIMD-75 gun used on the Minotaur series of vehicles, the Ogre's sub-turret has a powerful multi-spectrum optical targeting system for use with the main gun. The addition of the FIMD-75 cannon allows the Ogre to effectively engage enemy light armour and infantry units without committing its main gun, in situations where friendly units are already heavily engaged. Furthermore, the vehicle equips two more FIMD-20 PDS systems on either side of the vehicle, at the rear. These PDS systems were considered an essential additional component of the Active Threat Response system, especially in urban environments.

The Ogre entered service in 4405 A.D and is expected to be in service until at least 4800 A.D, as a replacement is not considered likely unless ATIS is engaged in a protracted ground campaign, of which so far, it has not. The vehicle has seen active use during the Battle of Helia, and is extensively used by the IPF units operating in the Ruins of Eridonia.
