The '''O74''' is a family of {{wp|main battle tanks}} and {{wp|armored fighting vehicles}} of [[Zacapican|Zacapine origin]] which first entered production in the early 1970s.


==Development History==
The design of the standard O74 and most of the subsequent variations originates in NTT 102 (''Neyeyecoliztli Tlayolteohuilli Tlaxeloliztli 102'', "Experimental Design Division 102"), a state funded military engineering institute located in the [[Zacaco Republic]], Zacapican. NTT 102 has been responsible for many offerings in the realm of Zacapine military vehicles ranging from light reconaissance vehicles to heavy self-propelled artillery pieces, however its most well known creation is the O74 main battle tank which has served in the Zacapine armed forces for 50 years and been the basis for countless variants used across many military applications. The O74 also represents the most widely exported of NTT 102s creations and one of the most exported pieces of Zacapine military equipment. NTT 102 is no longer involved in new MBT designs since the acceptance of the [[O17]], the replacement for the O74 family designed by NTT 57 in the [[Aztaco Republic]]. However, NTT 102 remains involved in designing other types of military vehicles such as IFV and APC vehicles for the Zacapine military.

;YCT Nagual
: Yaoyocamatetl Tepozzo ''Nagual'' is an armored fighting vehicle design used in the infantry fire support role. It is produced through the conversion of older O74 MBTs, replacing the original turret with a purpose built model armed with two 30mm automatic canons, one automatic grenade launcher and four {{wp|ATGM}} launchers. The YCT is also fitted with additional ERA fixed over the O74 hull, as well as modernized sights and targetting systems. The YCT is treated as an upgrade conversion package to the O74 and is exported to O74 users internationally. It is well suited to urban combat due to its suite of weapon systems and superior protection compared to equivalent {{wp|infantry fighting vehicle|IFVs}} due to the O74's base armor with added ERA protection against shaped charges with some protection against anti-tank kinetic penetrators.

;O74 Tzitzimitl
:[[Zacapine Army]] {{wp|multiple rocket launcher|MRL}} built on O74 hull equipped with a 220mm rocket launcher weapon system with 30 launch tubes. O74 Tzitzimitl not exported to any country and is only utilized by the Zacapine armed forces as {{wp|self-propelled artillery|self-propelled}} {{wp|rocket artillery}}. The launcher of the O74 Tzitzimitl is capable of firing rockets fitted with {{wp|Thermobaric weapon|thermobaric warheads}}. It is designed to attack entrenched and fortified enemy positions and light vehicles.
;O74 YN
:Modernization package for the O74 developed in 1997, the most common O74 variant in active service with the Zacapine army and others in present day. Includes an improved welded turret, modernized ERA and countermeasures, new thermal sight for the gunner and addition of CITV commanders thermal sight.
;O74 YNA
:Upgraded version of O74 YN with the addition of a modern {{wp|Active_protection_system#Hard-kill_measures|hard kill active protection system}} and set of laser warning receivers. It was the most advanced armored vehicle in the Zacapine armed forces prior to the entry of the [[O17]] into active service.
;O74 YQ
:An alternative modernization package to the O74 YN which was rejected due to higher cost and production issues. It features heavy modifications to the hull including the relocation of the engine to the front of the vehicle in order to open up internal space for a passenger bay in the rear of the vehicle capable of holding infantry dismounts, converting old O74 main battle tanks into MBT/IFV hybrids.
;ZMCT
:The Zazamalhuicamatetl Tepozzo is a heavy infantry fighting vehicle based on the O74 YQ prototype. It incorporates the same turret model as that of the YCT Nagual as well as the heavily modified hull of the O74 YQ. It has the same armament as the YTC Nagual with one additional automatic grenade launcher and one additional 7.62x51mm machine gun. The modified hull accomodates 5 dismounts in addition to the 3 vehicle crewmen, giving it a total capacity for eight personnel.
