I generally retire/re-role any MG units in the core when past the desert and fighting in Europe. Generally not enough fields of fire to make them worthwhile. You want to be able to see past 600m (LMG range) with a decent field of fire past that.

In the Desert, and Russian open fields - well worth having in the core.

With a German campaign though, I usually change them to something else when being pushed back by the Soviets, but you do get occasional places they can be useful - however then only bought as support units for the one battle if it is flatlands or on a commanding height and good visibility.

They are wonderful tools for stripping off the tank riders the AI likes to use, especially on bunched-up lumps of them!
