A simple buff idea to the SP1C and the HWK12

Einzelganger7: In my opinion what the whole branch needs is shell velocity and/or a bit higher alpha depending on the tank, for example make the Spähpanzer C1 with 800 m/s shell velocity and same alpha, HWK 12 with 800m/s shell velocity and 280 alpha with standard/premium ammo (360 HE and 90mm of pen), RU 251 with 320 alpha while using standard/premium ammo (HE 420 alpha and 102mm pen), and finally Rheinmetall Panzerwagen with 360 alpha using standard/premium ammo (HE 460 alpha and 120mm pen).
