[SG] Firing & actions

I don't really see this as cheesy at all. Since IAVR's are one shot
weapons,
they could only do this once. My friends and I use similar tactics
regularly. Remember, one turn in SG is about 5 minutes. That's plenty of
time, even in a combat environment, to fire a volley with a rifle, then
shoulder a LAW and let'r rip.
