[SG] GMS question

A point came up the other day and I couldn't find it spelled out in the
rulebook one way or the other.

Can GMS target infantry in SG2 ?

The ambiguity stems from the phrase which describes the firing
mechanism.
It says the range die is not used in the opposed roll off, but the ECM
die
for the target vehicle.  Later on the same page, there is an outline of
how
heavy weapons attack squads (D8 impact versus each and every squad
member).

So, can a GMS be fired at a squad ?  If so, what is the squad EW ?  Are
all
memebrs hit with D8 impact, or is one hit, or are some hit (divided by
EW
die size) ?
