GMS in SG2 [for Oerjan]

Follow up to something you wrote earlier I meant to comment on.

In SG2, the IAVR has infantry fire range bands (depends on quality of
unit - 6", 8", 10", 12") and adds a FP die equivalent to a SAW to fire
against infantry. A GMS probably could be fired against infantry, though
no mechanic exists (really). It would probably count as an area-weapon
attacking with D8 penetration against each member of the squad. This is not at
all the same as the impact of an IAVR, though both have the same
anti-armour effects. And GMS is rather different in that it has
across-the-table, line-of-sight range with no range modifiers - only ECM
affects it.

Maybe that helps?
