History
The
Mecatlacuhtlazacani-Huei Ēpōhualli-Omōme ("Tracked Combat Transport-Heavy, 62", commonly known as the MCZ-H62), was a cannon-armed armoured troop transport developed in the early 1960s that is widely considered the first Infantry Fighting Vehicle of the Divine Monarchical Order. The MCZ-H62 was designed to replace the MCZ-Z54 APC in armoured and mechanised units, where the thin armour of the 12-ton transport had proven concerningly vulnerable to the Ruanan 15.1mm VHMG that equipped a number of rebel vehicles during the Vangaelic Civil War, with the vehicle's own 8mm MG showing to be of limited utility against enemy APCs and lightly-armoured vehicles. While this was considered acceptable for second-line vehicles and forces not expected to regularly engage first-line forces in any major conflict it was considered insufficient for first-line forces expected to encounter enemy APCs armed with HMGs, and so the requirement for a vehicle capable of transporting a squad of infantry while being protected from VHMG fire and carrying a weapon heavy enough to take out light armoured vehicles or entrenched infantry was submitted to the Ordan State Armouries in 1959, with the expectation that this would replace the MCZ-Z54 in appropriate units once it entered production.
Design work began in 1959, with proposals to adapt either the MCZ-Z54 Armoured Personnel Carrier or TNT-T48 Light Tank chassis for the new vehicle, though both would ultimately be rejected as the resulting proposals would have an unacceptably small transport capacity. Instead, a clean sheet design would ultimately be chosen. The acceptable armament would also see a range of discussion; the smallest considered armament would be a 13mm Heavy Machine Gun (ultimately decided against due to its lack of existing service within the DMO), while the largest would be a 57mm Autocannon (the armament of the TNT-T48 Light Tank, at the time in the process of being replaced. This would ultimately be rejected due to concerns that any turret capable of containing the gun would take up a large section of the crew compartment). 20mm, 30mm, and 40mm autocannons would be subsequently decided between, all three being in service with different parts of the Ordan military and small enough that designers felt a suitable turret could be created for the gun. Of the three, the 20mm autocannon would ultimately be decided upon due to being powerful enough to destroy all non-tank vehicles in known Ruanan or Nagi service while being small enough to allow for large quantities of ammunition would not itself take up passenger space.
The first test vehicles would be put together by 1961 and would be submitted to the 1961 Spring Manoeuvres for testing. Weighing just over 18 tons, the prototypes would prove to be promising though not without complaints. The vehicle was equipped with the same 240hp diesel engine as the MCZ-Z54 it was replacing, giving it a power-to-weight ratio of less than 14 hp per ton and causing it to be outpaced by virtually every other vehicle on manoeuvre. Additionally, various issues would be raised with the prototypes' reliability, and the difficulty of entering and exiting the vehicle's roof hatches over the tracks, as well as the cramped nature of the crew compartment and tight confines of the rear entrance door. The design would be tweaked over the following year and resubmitted again in the 1962 Spring Manoeuvres, where the replacement of the engine with a much more powerful 400hp engine and the addition of sections of side skirting over the tracks by the roof hatches to facilitate safer embarking and disembarking (the sections designed to fold upwards during maintenance to allow access to the tracks behind them) would resolve several of the outstanding issues, though the cramped nature of the crew compartment was unchanged and the rear passage became even more cramped due to the enlarged engine bay, and additional concerns would be raised about the suspension and transmission's performance at the higher speeds now reachable with the new engine. Despite these concerns the design would be accepted for general production shortly after and the first delivery would be made in Autumn 1962.
The design would be received generally positively by the crews, though the concerns raised about the cramped conditions would be repeated as the vehicles entered general use, with many units ignoring the rear passage entirely as an egress point in favour of using the passage as a storage area, and entering and exiting the vehicle entirely through the roof hatches. The vehicle's thick armour, a full Ordan Inch (approx. 30mm) of rolled steel on the frontal and side arcs, would render the vehicle immune to most weapons carried by expected opposition at typical combat ranges at the time of its introduction; though the increasing adoption of guided anti-armour missiles and the subsequent deployment of cannon-armed IFVs in other national militaries would reduce the advantage of the vehicle during its service. Attempts would be made during the 1960s to give the MCZ-H62 the native ability to fire guided ATGMs, but various factors (including the small size of the turret and reluctance to obstruct its field of fire by mounting a missile launcher directly on the hull) would make this infeasible without negatively impacting the vehicle's transport capability.
The MCZ-H62 would first see combat during the Cetian Intervention of 1968. The Cetian President, Zuri Babatunde, was facing a long-running Krasimirit insurgency and invited Ordan forces to assist with peacekeeping efforts in the early 1960s. Ordan forces, though initially limited to advisors and special forces, soon expanded in number as Cetian forces proved unable to contain the growing Krasimirit threat. Among the forces deployed were the 2nd Battalion of the 2nd Eagle Guard Division, as part of the long-standing
Tlayaomachitia policy. The 2nd Eagle Guard Division, recently equipped with the MCZ-H62 IFV, soon found themselves engaging in combat during patrols in the Cetian desert and shrubland, where the vehicle's near-immunity to weapons that were not dedicated anti-armour weapons or large explosives and its heavy cannon's ability to punch through the light vehicles and improvised entrenchments favoured by the rebels saw it gain great favour among the troops, though the cramped interior meant the passengers would often travel with the roof hatches open during patrols, something that saw several squads of infantry take casualties from grenades and mortar fire during ambushes.
D Squad, 1st Platoon, 1st Company, 2nd Battalion were first deployed to Cetia in Autumn 1968 alongside the rest of the 2nd Battalion. A mechanised infantry battalion of the elite
Icōme Tlayacatl Yaocuauhtli ("2nd Division of the Eagle Guard"), they were equipped with the most modern infantry equipment available to the Ordan army, including the MCZ-H62 Infantry Fighting Vehicle and the recently-introduced CHT-T64 Assault Rifle and TPT-T64 Light Machine Gun, the first weapons developed with the 6.5x54mm Ruanan cartridge adopted in the aftermath of the Vangaelic Civil War to replace the 6x40mm Ahuatetz and 8x60mm Cuauhtic cartridges in general use. These weapons came as a shock to the Krasimirit rebels who, used to facing the ill-equipped Cetian forces (mostly armed with weapons from the first Great War, seized from the
Tercio de Extranjeros ("Army of Foreigners", the Espanian colonial forces) following the Second Great War that led to Cetian independence), had advanced to seize control of much of rural Cetia. The Battle of Rohana in October 1968 exemplified this, with over twenty thousand rebel troops defeated in an attempt to seize the town of Rohana by three battalions of recently-arrived Ordan troops (at the time, the majority of Ordan forces deployed in the region) thanks to their mobility and uncontested air support. However, with open battle shown to be ineffective by the months after the Ordan deployment, the rebels would take to guerrilla warfare on the scrubland and deserts of rural Cetia. In response, the Ordan forces began a style of warfare known as
Yaotlaixtlahuatl ("Savannah War"), that emphasised rapid movement and the seizure and denial of key strongpoints over the traditional wide-front mass warfare favoured on Akatet.
D Squad, along with the rest of 1st Company, would engage in many long-distance patrols during the course of the Intervention. Typically deploying alongside the rest of their platoon, D Squad would engage rebel forces on several occasions, and would receive decoration for their conduct after their involvement in an ambush that saw two of their platoon's vehicles disabled by an improvised explosive. Facing mortar and sniper fire from rebel forces, D Squad would take point on a charge that would see the ambush broken, over thirty rebels killed and several mortars captured, with the squad only taking two light injuries in return.
