MI1M3 Quadriiuga

The MI1M3 is a upgrade of the original Quadriiuga, featuring slightly thicker RHA plates while retaining its extreme slope, enabling it to resist autocannon fire and older APDS and APC rounds. The armor on the sides and roof were also modestly thicker. A spall liner was also added to give enhanced protection to its occupants.
The upgrade was planned for awhile, with the intention of giving the Quadriiuga newer more compact electronics set that was found on vehicles like the Nombril and Fess. Experience in peacekeeping have found certain formations lacking in dismount numbers, which has since prompted re-evaluation of the army's organization. Especially with GPYF and its breakaway states coming to a negotiated settlement, the army have decided to downsize from the current 77 total mobilized strength to approximately 65 mobilized divisions. The active component will go from approximately 25 to 20 divisions as well. This will free up vehicles and manpower to strengthen existing formations for more dismount capacity. Army planners considered this a good opportunity to modernize some of its oldest APCs in service to take advantage of the reorganization.
The original upgrade plan would have kept the vehicle at the same cost per unit, but the army decided that the plan was too conservative to warrant upgrading.
Instead, they went with a more ambitious upgrade, with the biggest upgrade focused on its firepower and visibility. The vehicle received a new remote weapon station. The old medium-pressure revolver-style 30mm autocannon was kept, but now also complemented by a 12.7mm heavy machine gun and a RR3M1 ATGM launcher, same as the ones used by infantry. The ATGM gave the vehicle a significant punch, capable of destroying even older generation tanks, though still incapable of going through modern MBTs. The single shot and need to be reloaded from the outside still makes it less capable than dedicated IFVs. However, for a simple, easy to drive, and mass producible vehicle, the army can amass ATGM fire for its infantry formations.

The other major improvement was the vehicle's overall visibility. The RWS features a newer gunner's sight and a independent thermal viewer with 360 rotation and elevation, capable of moving separately from the weapon. This enhances the gunner's spotting capability. This change meant the CITV was moved separately from the RWS and in front of the vehicle commander's hatch, replacing one of its vision blocks. However, the new CITV is the same as the one on the Fess main battle tank, a Gen 3+ system, making it a overall improvement.
The dismount commander at the back also gets a new cupola, also adopted from the Fess main battle tank, with 12 double vision blocks giving the dismount commander excellent 360 degree visibility, and the double vision blocks providing a horizontal and an upward 45 degree vision, for a near hemispheric visibility while buttoned up. This new cupola also has the ability to be in the open-protected position. Improved situational awareness allows the dismount commander to decide course of action before exiting the vehicle, improving overall reaction times and survivability. Designers also wanted the vehicle commander to get this new cupola, but it proved too big to fit with the new CITV location in the way. As such, the older cupola was kept.
There are also five sets of three vision blocks for the rest of the dismounts, so they too can see outside and understand what their dismount commander is referencing to when giving orders prior to exiting. Two of the firing ports had to be shifted slightly to make room, but the same amount were kept for fighting buttoned up.

The last changes were replacing the older halogen head and tail lights with new LEDs. LEDs have been the standard for all new production vehicles, though many older vehicles still use halogen bulbs. The smoke dischargers also had to be moved forward so the repositioned medium-pressure 30mm autocannon could clear it.

Despite all these changes, per unit cost only increased slightly and remains affordable for mass production during wartime. The upgrades reflect the continued importance of the vehicle despite its humble origins as a cheap mass produced APC for reservists. Its high dismount capacity, fast speeds, good protection, and large rear ramp makes it a favorite even among active formations.
