Sighting Question

[low_bidder]

"The question was why you cant shoot the target you can see. To put it simple. "

Out of shots
Out of the right type of ammo
Retreating or routed
Out of range
The AI doesn't like you (joke, J_O_K_E, joke)
That weapon slot is turned off ( there is an asterisk there on the main screen in the shots left data field)

Or some other reason I have forgotten.
Walk the cat back. To shoot at any target you need an LOS, shots left and the right kind of ammo. Just because you can see the target doesn't mean you have LOS from your shooter. The way to tell that is looking at the targets line. If it has 0 instead of a whole number then THAT shooter doesn't have LOS.
Now the shooter might have LOS to the hex and not LOS to the target, I don't recall experiencing that, but the fog of war thingie make anything possible. Ever get a critical hit of +2 with your weapons penetration of 9 for a total of 11 on an armor of 3 and have the shot bounce? Then the target op fires and blows a penetration 4 round thru your front armor of 9? Shit happens. Only it's called fog of war in SP.
I don't particularly like it but I'm used to strange stuff happening in SP. I just hope it happens to the other guy and not me. Although in the end it all balances out. I hope.....
