Gents, the AI in WOV is not "scripted" in the same manner as other PC titles. Rather AI bombers possess the intelligence to bomb and fighters to intercept all on their own. Added to that is a degree of randomness in the AI's response. The same number of planes will not usually fly in some scens/SAM's activate and/or both.
I just played this scen and scored an immediate major US victory. A half flight of MiG 17's launched from what I estimate to be Phuc Yen.
All targets other than the Vinh POL Storage facility possess AAA as evidenced by their gray range circles.
So lads what's happening in this scen is: 1) If you hear AAA it's firing but be sure to check the map as the 3 target points are a long way in between to where the action may be; 2) MiG's can scramble - however, as the scen stands there aren't that many of them to do so! 3) There's no VPAF SAM assets on map to light up!
Those are the issues here and I'll see if I can have these looked into for the next update. Historically this raid caused massive damage with 2 US losses to AAA only. Therefore, the scen may be "accurate" as is.
For those having trouble winning - check your assets for multiple bomb loads - you'll need to order subsequent bombing assignments to release those as only one bomb type falls per pass. Also remember the importance of recon.
