Re-Discovered after 20+ years, have some rules questions

[fogrob]

Hello all. As I said in the title, I had first edition many years ago when I was in high school. I've recently thought about trying to run it and while doing some solo play testing, I've come across some rules questions. (I'm sure I'll have more which I'll just add here)

1.) I have 2 NPC's taking cover behind an unarmored cargo vehicle. They are being shot at by the PC's. I'm unsure how to work this. Does it count as an armor equivalent cover and I just work through the vehicle damage chart? Or, should I just make it easy and count it as target obscured and just halve their die roll?

2.) I have an NPC running from one cover area to the next in an attempt to flank the PC's. How do I handle that? My idea was to give the PC a choice...They can shoot at the target without cover, but with the obscured target penalty. If they choose not to take the penalty, they have to deal with the targets end move cover.
