Hi folks!
1st - thanks seldom for already answering a bit of it.
ViDe seperates the LMG and the HMG.
The squad based MG-42 is of course the same weapon as the HMG, the usage is different.
As always in ViDe a bit of abstraction is called for.
MG-42
LMG 3 48” 2xD6+1 Set Up/3, Suppression
Used like this:
Properly set up with tripod and all you get the HMG weapon team:
MG-42
HMG 3 48” 2xD6+1 Set Up/4, Suppression
Support Teams have additional rules that reflect loaders etc. Same weapon but slightly different once set up properly.
