DSII: More questions

I know some of these questions have been discussed before, but I can't 
remember the answer.

1) Is moving the only way to remove Under Fire Chits?  I couldn't find 
anywhere that said they were removed after 1 turn of a unit not being 
fired upon.

2) Does a required retreat from a close assault count as the activation 
for the retreating unit?  How do you work dismounted infantry getting 
back into their vehicles to retreat?  Can an assaulting unit follow-up, 
even if the retreating unit is now out of the 6" range (mounting in 
vehicles & dashing off)?  

3) Can Powered Armor elements be purchased as specialty teams (ie, a 
GMS/L PA element)?

4) How do you work IAVRs firing at a vehicle with APFC & Reactive armor?

Reactive armor allows only Red chits & APFC allows only Yellow.

5) For clarification, do all specialty chits count against artillery 
targets?

That's it for now.

Thanks,
Nils
