I found this Bofors poster of the Indonesian Armed Forces' day commemoration of 1986. The poster suggests this is a SPAAG vehicle named Trinity, or at least some parts of it were. Quick search results in several examples of the Bofors Trinity turret being installed on the MOWAG Shark chassis. But the turret design seems a bit different from the actually-built turrets. I was searching the detailed specification of this turret, to no avail.

Looks like the naval turret adopted for land:
 
The Mowag Shark is an amazingly large family of armored vehicles that was designed by Mowag in 1978 and the first prototype built in 1981. Basically introduced as an enlarged version of the Mowag Piranha 8X8 with more protection, the Shark was intended to be a wheeled tank . and not really an IFV or APC like the Piranha, more circumstantially for the tank destroying role, but they also offer great role versatility due to the many turrets that can be fitted. ANDThe chassis only weighs 16 tons and if it is intended to carry a turret of up to 6 tons it would give a weight of 22 tons but the weight was carefully studied to give optimal agility with a 5 ton turret (the center of gravity would be exactly in the center of the vehicle). The Shark have a high quality suspension and high protection. but this came at a cost that was the same price. the Shark was much more expensive than the Piranha, which was often capable of carrying the same turret. Despite a large publicity campaign and tests in different countries, including Germany, Canada and Switzerland, no orders for the Shark were received. Prototype 3 was built between 1981 and 1983 and mass production was ready in July 1983, but this production never took place.

in this suggestion we will focus more precisely on the Mowag Shark Trinity. this vehicle was built in partnership with Bofors. this version was built from 1984 but at that time it was just a test bed, the true origin of the Trinity came in 1985 when the turret was receiving its fuselage to protect the mechanics. the purpose of this development was purely for export, as the Shark was at the time the best armored vehicle offered for export. the demonstration of the Trinity turret on the Shark was giving the vehicle and turret a better chance of being exported. Bofors intended to export this very turret to Austria, Brazil, and also produce it for the Swedish Army. Not on the Shark but on the Steyr 4K 7FA (Austria), Charrua II (Brazil) and Strv 9040 (Sweden). Making the Shark a pure private company. The test continues and seems to be successful. it was introduced to the public in 1988. The Shark was presented as the base on which the Trinity would normally be assembled, and is often highlighted as such. but no buyer shows real interest.

Firepower

The main armament is a 40mm Bofors Trinity L/70. this armament is an upgraded version of the 40mm L/70 found on some vehicles in the game. but they feature a Solothurn muzzle brake which greatly reduces recoil. this increases the accuracy of the weapon that would otherwise be ineffective at further range. the turret is truly advanced. with search radar with a detection range of 20 km. Track anything with a speed between 0 and 4320 km/h and a Lear Siegler output speed radar. In addition, the turret also features a laser rangefinder, night vision, thermal vision, digital computer that can program the ammunition's proximity fuze while firing at a moving target to maximize the chance of a kill.

Movilidad

El Shark está propulsado por un motor General Motors Detroit Diesel 8V-71 T que desarrolla 530 hp a 2500 rpm, esto estaba destinado a dar un peso de potencia de 25 hp / tonelada con un peso de 21 toneladas. El tiburón está diseñado para ofrecer una alta velocidad en terrenos irregulares con una velocidad máxima de 80 km/h fuera de la carretera y una pendiente muy pronunciada del 70 %, eso significa que el Tiburón era básicamente capaz de cazar a su objetivo en cualquier terreno . La caja automática Allison modelo HT-750 DRD (de 5 velocidades de avance y 1 de retroceso), se acopla a una caja de transferencia auxiliar de dos velocidades y cuatro diferenciales autoblocantes que pueden ser acoplados, de dos a dos o los cuatro, neumáticamente por el conductor según las condiciones del terreno o las necesidades de conducción. E l centro de gravedad con una torreta de 5 toneladas fue cuidadosamente estudiado para colocarse exactamente a 1,25 m del suelo justo entre el 2º y el 3º eje, que es básicamente el centro del vehículo. Cada rueda tiene suspensión independiente, los dos ejes centrales no son orientables; su suspensión está construida con amortiguadores y sus ruedas van montadas sobre brazos oscilantes conectados a barra de torsión. el primero y el último son orientables y asistidos hidráulicamente y They have fork suspension, oversized coil spring and hydraulic shock absorber. The prototype mounted Michelin 13.00 x 20 tubeless tires.

Protection

The Shark's protection was intended to allow its use fairly close to the battlefield. but keeping a good weight carefully studied to give a perfect balance on the vehicle. the armor offered protection against armor-piercing 14.5mm KPV or 155mm HE shells at 10m on all sides. the armor was constructed of high-strength armor plates and sloped on all sides to improve protection while maintaining light weight. this makes the chassis similar in protection to the Italian Centuro B1 (without additional armor). this makes this vehicle similar in protection to a light tank, except for certain tanks like the Russian BMP which have some pretty terrible armor. in the case of the Trinity Turret, there is no data on the armor.

* this barbeque armor thickness is estimated based on the reported protection efficiency and knowing that the armor is made of HHRhA.

'The Shark is powered by a General Motors Detroit Diesel 8V-71T engine developing 530hp at 2500rpm, this was intended to give a power weight of 25hp/ton with a weight of 21 tons. The Shark is designed for high speed on rough terrain with a top speed of 80km/h off-road and a very steep grade of 70%, that means the Shark was basically capable of hunting its target on any terrain. . The Allison HT-750 DRD model automatic transmission (5 forward and 1 reverse speeds) is coupled to a two-speed auxiliary transfer case and four self-locking differentials that can be coupled, from two to two or all four, pneumatically. by the driver based on terrain conditions or driving needs.
The center of gravity with a 5 ton turret was carefully studied to be placed exactly 1.25m above the ground right between the 2nd and 3rd axle, which is basically the center of the vehicle. Each wheel has independent suspension, the two central axles are not steerable; Its suspension is built with shock absorbers and its wheels are mounted on oscillating arms connected to a torsion bar. The first and last are steerable and hydraulically assisted and They have a fork suspension, oversized coil spring and hydraulic shock absorber. The prototype mounted Michelin 13.00 x 20 tubeless tires.'
