OP fire in general?

[Digger]

Recon units wll NOT improve the chances of OP fire, they do have better spotting capabilities, but this is calculated at the start of the turn, for the puposes of determining what units you can see.

As to why units do or don't OP fire. It is a simple mathematical calculation and with any game there is a chance of sucess or failure. The only control you have is to set your range settings and hope for the best, or if you are like me turn it OFF for most.
