Variants
- YCT-1 Nagual
- Yaoyocamatetl Tepozzo-1 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 ATGM launchers. The YCT-1 is also fitted with additional ERA fixed over the O74 hull, as well as modernized sights and targetting systems. The YCT-1 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 IFVs due to the O74's base armor with added ERA protection against shaped charges with some protection against anti-tank kinetic penetrators.
