Shark.

Three prototypes were constructed, with trials reported in Switzerland, Germany and Canada; these were trials, not service adoption. The German reference dates all three to 1981, while the English account dates the later two to 1983. The hull is reconstructed from the supplied museum front and ADATS side photographs; the missile turret is excluded. The requested GDD-BOE turret is reconstructed from original Oerlikon GDD-B brochure drawings, a related two-man installation shown on a different chassis. That brochure explicitly specifies 35 mm, while the supplied German account calls the Shark installation 30 mm. The requested 30 mm gameplay autocannon is retained, with the precise prototype turret configuration unresolved.

The eight shared Zander wheel assemblies are scaled around their pivots, with front and rear axles steering oppositely and the middle two fixed. The hull dimensions and 390 kW/100 km/h/22-tonne figures follow the supplied record. Wheel spacing, track, turret scale, rear engine deck and rear lamps are photographic/proportional reconstruction, not verified engineering dimensions. Torque 1490 Nm is the calculated equivalent at 390 kW and 2500 rpm, not a sourced peak-torque measurement. Grip 0.84, drag 4.1, steering 1 and acceleration 1 are gameplay tuning. The shared mass validation ceiling was raised to 25 tonnes to retain the researched 22-tonne mass. Manufacturer brochure rear smoke dischargers are represented as three per bank with the normal shared reload. Camouflage is a photographic approximation, not a factory stencil.
