buy the gun, then turret and then hull (I’m genuinely sorry there’s no better options for hull)

the hull is terrible but all the other options also suck (or are incorrectly priced in the case of the Ru 251) at least this allows you to complete wheeled daily missions.

the turret has some armour, a good rangefinder, roof 12.7mm HMG and a good reload multiplier.

the gun has good penetration and great velocity with a longer reload (not as long as the 8.8cm Ikonisch).
