thing to note about CCIP though is that it is definitely not infallible, it simply puts the ordnance about on target, not on the 1x1m circle I was aiming at. This is more pronounced when trying to hit point targets with rockets or bombs.

  Opps, this is actually a FOW issue.  My limited testing reveals that FOW is overwriting speaker to empty string on various units (including IFA3 and vanilla units too), which results in default game voice (which is English speaking).  I did a bit of searching and found that this was indeed acknowledged by Giallustio here on 4/24/18.  So, nothing to do with IFA3...

  You no longer get that target lead indicator for ground vehicle targets, that behaviour has been removed via one of the main stable branch patches awhile ago. Now you still have a CCIP indicator which accounts for range but you have to manually lead moving ground targets yourself.   You only get a target lead indicator for air targets and only certain vehicles provide this functionality in the first place. I believe the Wipeout and Neophron attack jets don't provide this functionality while the air superiority/multi-role jets and SPAAGs do.

I concur with the general feeling, this is a quite beautiful terrain!....It's also compatible with the vanilla versions of Sullen Skies.
