War Thunder: The SAu 40 is Meh

The SAu 40 is a tank destroyer equipped with a 75mm cannon and a turreted 7.5mm machine gun. The SAu 40 has a crew of 3, 1 on the right of the cannon and 2 on the left with one manning the turreted machine gun.
The SAu 40 has access to 2 types of rounds:
• (APHE) which has 75mm of penetration at 100m
• (HE) which has 10mm of penetration at 100m
The SAu 40 has a maximum speed of 37km/h (RB) and a reverse speed of 4.8km/h (RB). The SAu 40 reached 14km/h fairly quickly with a reduced speed gain from 14km/h to 23km/h and a further speed gain reduction from 23km/h to 37km/h. The SAu 40 has (neutral steering) which slightly increases the SAu 40 combat capability.
The SAu 40 has a maximum armour thickness of 40mm and a minimum thickness of 8mm. The SAu 40 frontal armour is fairly bad with flat sections in front of the driver and gunner positions allowing for the armour to easily be penetrated.
Key:
(HE) = High Explosive
(APHE) = Armour-Piercing High Explosive
(RB) = Realistic Battles
(Neutral steering) = A mechanic of tanks where one track runs forward and the other runs backwards this allows the tank to turn on the spot
