You Gotta Love Halftracks II

[von Manstein]

By the way the HT (again): most of them had mounted MG so shouldn’t they had the same firepower as MG squad in CS?

When platoon dismounted HT they didn’t take that MG with them and I don’t believe that only driver stayed in HT and there was no one to use it.
Correct me if I’m wrong but whole idea of HT was to get infantry safe in to battle AND support it by MG during assault.
