War Thunder: The Pbv 301 is Meh

The Pbv 301 is a (SPAA) equipped with a 20mm auto-cannon. The Pbv 301 has a crew of 2, 1 in the turret and 1 in the hull.
Despite the Pbv 301 being labelled as a (SPAA) in war thunder its actual application is an (IFV), Pbv which stands for “Pansarbandvagn” which translates to “Armored track vehicle”.
The Pbv 301 entered service in the 1960s and was built on old Strv m/41 S-II hulls with heavy modification.
The Pbv 301 has access to 3 types of belt containing 2 types of round (AP-T) which has 40mm of penetration at 100m and (HEFI-T) which has 4mm of penetration at 100m:
• Default which is (AP-T), (HEFI-T), (HEFI-T)
• slsgr m/42 which is (HEFI-T)
• slpgr m/42 which is (AP-T)
The Pbv 301 has access to smoke grenades which are launched from the front of the hull.
The Pbv 301 has a maximum speed of 45km/h (RB) and a reverse speed of 6.8km/h (RB) the Pbv 301 reaches 27km/h fairly quickly but has a reduction in speed gain from 28km/h to 45km/h so on most maps you probably will never achieve its top speed.
The armour of the Pbv 301 has a maximum armour thickness of 50mm and a minimum thickness 8mm thick. The 50mm armour is located in front of the transmission with the rest of the frontal armour being 20mm thick. 7mm machine guns can penetrate the Pbv 301 side armour and 12.7mm machine guns can easily penetrate your frontal armour.
