One can already do that with Raid section, one can pick 2 LMG (brens) or 2 "assault rifles" (vickers) what one can not do is pick a combination of weapons.
I quite don't follow you.
When you say "Yes the is no positive benefit of picking an M1919 and a BAR for riflemen either or is there?
Nice theory but false..."
you tried to point out that nowadays riflemen picks up both M1919 & BAR at the same time to be stronger inf. right?
I'm just pointing out that the reason behind of combination of both two weapon is because picking up two M1919 is prohibited ATM due to balance issue. If it was allowed, all would have pick two M1919.
I hope we are on the same page so far.
Read at the context and as of what you have pointed out about BARS does also apply to picking Bren or V-K.
Picking 2 Bren UKF units (accept commandos) long range static unit, picking 2 Vickers make them mid range oriented with decent moving DPS and combining the two make the unit a flexible all around unit.
In sort there are benefits not matter which roots one follows.
AFAIK UKF still can mix V-K with bren from M3 supply half truck.
And trust me, V-K is always better choice to use when you have option to pick one, There is a reason for bren cost 45 muni.
If
https://coh2.serealia.ca/ still is correct, V-K also provides higher dps in long range than bren, and ables to fire while in move.
So yes, I second @Katukov on the fact that "there's not a single positive benefit to mixing brens and vicker Ks
not
a
single
benefit."
Just pick V-K when you can. Unless you are absolutely can't pay for that extra 15 muni. (Which is never)
