OT-74 tank

(OOC: I know it looks like a T-62 but I'm too lazy to make my own stuff and plus the tank profile is what I'm looking for)

OT-74 Tank
Type: Main Battle Tank

With the entire tank fleet of Oceanian aging and becoming obsolete to the point where modernization programs won’t cut it the WOSDRT has started designing a new tank to replace the T-55, T-62, and T-64 in frontline service, however, the Yugo M-84 and T-72 tank will however stay in frontline service and still see modernization programs

The tank was designed with an autoloader based on the one found in the T-64. With this it allows the reloading process to be much more efficient and quicker than having a loader. The autoloader is located at the bottom of the tank with plates around it to prevent the crew from getting injured and things from getting lodged in it.

The design was decided to use the abundance of T-62s however there were issues ranging from not enough space to mount the autoloader and a larger gun to certain things that needed to be removed to accommodate other things because of this the turret was redesigned to be a little bit bigger while still having the low profile dome shape and the hull was stretched out to accommodate the autoloader, ammo and the engine. Using this design allowed the tank to have a slimmer and smaller profile.

The main armament is a 125mm gun due to having a large amount of ammo in the 125mm caliber however 2 variants are equipped with a 115mm or 120mm gun they will either see frontline service or be sold as an export variant.

Gunner has access to 3rd Gen NVGs, FLIR, and Thermal sights, advanced targeting systems that allow the gunner to track multiple enemy targets

The autoloader takes about 5 seconds to reload from the carousel ammo rack. The tank holds about 40 rounds with 30 shells in the carousel loader and 10 in the front hull stowage

Cartridge ejector located in the rear ejects spent casings instead of leaving them in the tank

Friend-and-Foe identification systems allow tanks to tell who is who and relay the information to other tanks with the same equipment (only available on the T-72, M-84, and OT-74)

Communication Jammers allow the crew to jam enemy radios and other forms of communication and of course, they can turn on or off

Tor-Daz soft-kill APS could be installed to prevent ATGMs and alert the crew that they are being targeted.

Slugger Hard-kill APS could be installed to destroy enemy projectiles.

A laser rangefinder can reach up to around 8000-9000 meters (8km-9km)

Commander Equipment

NKT-3
Day-Night periscope
Day: 5x magnification 10-degree field of view
Night: 4.2 magnification 8-degree field of view

The scope comes with 2 modes active mode and passive mode.
In Active mode, the IR light is turned on and paired with the Periscope it can spot targets up to 5000 meters in passive mode only the Periscope is used and can spot targets up to 800 meters.

The NKT-3 had separate optical channels for the night and day viewing modes. In the daytime channel, the two eyepieces lead to separate apertures to provide stereoscopic vision, thus providing depth perception. For the night channel, the optical channel from the two eyepieces was merged to view from a single aperture lens.

The control panel on the sight, located just under the eyepiece, features toggle switches to turn on the independent stabilizer, one to turn on the sight heating system, and one to turn on the internal lamp to illuminate the viewfinder markings. There is also a dial switch on the right of these toggle switches to select between APFSDS, HEAT, and HE-Frag in the ballistic computer. The other controls of the sight remain the same as in the preceding models.
