LMG + Stahltruppen + Question...

I'm wondering about the point of mounting an LMG on a . Because sure, it's 5d firepower, but without the loader, it suffers a -1 to fire (since it's a team weapon)?

So, when stationary, it hits on 5+ and when moving on 6+.

Compared to a StG44Z, which gives you 3d firepower, at 4+ regardless of the carrier's configuration. It seems to me that this is more advantageous.
