I totally can’t understand why Gaijin just adds a useless SAP belt for Kugelblitz, except it needs more RP to get the APCR belt. What benefit does Kugelblitz? Those planes with MK103 need this belt more, HVAP and Stealth belts require too many SP cost sometimes, and SAP can be a very good alternative belt when you take bombs. It is also possible to replace the SAP with real APHE, which will make sense to add for SPAA and planes
