Currently, German MK103 ammunitions are not ideal, only has HVAP or AP-I for CAS. Both of them will cause MK103 lose its ability to counter air target, as the new suggestion is accepted, it is time to add a real APHE as MK103/101 new belt for CAS, which will improve the currently German CAS power, such as DO335B or HO229.
