Dang...
Why is it showing rerolls, but no boxes to check to reroll?
Honestly, insane as it sounds, the Highlander isn't nearly as thrwating with a 4/6 pilot under moonless night where physical attacks will dominate.
Also, unless some of those mechs specialize in night fighting, only the jumpers will be mobile. Take close assault jumpers to kick the convoy.
Because I haven't resolved the other 9/22 fight yet.
Also, there's two real ways to do this sort of mission:
1) Jump in a "ring" to keep any civilian "leakers" from escaping. The downside of doing this is that the enemy will have a chance to mass against a portion of the attacking force and hit it individually. Under moonless night rules where shooting is inaccurate, it also means that if the convoy "masses" in one direction to try and break out and move off the board, it can overload that section of the ring and the odds of us getting *all* the convoy is heavily reduced.
2) Jump right on top of them so they don't have the chance to react or mass in any given direction. The danger of this plan is that the convoy immediately goes "every man for himself" and busts out in every direction, and without the ability to shoot accurately, we're unlikely to be able to get them all before they break contact in the darkness (and chasing them down opens ourselves up to defeat in detail by pursuing escort Mechs).
(3) A "hybrid" approach is the worst of both worlds, since we can't set up a complete "ring" and so they can always make for the gap we can't cover, and the portion of our stuff that jumps into the middle will be heavily outgunned by the escorts. Thus, I don't even count it as an option.
My recommendation would be to to reroll Moonless Night first and foremost, and if we get lucky on that, maybe try to increase the map size to buy ourselves more time to intercept fleeing convoy traffic.
The one blessing here is that the Wind Condition is Calm. Which means no further piloting modifiers on the Hot Drop (actually...does Moonless Night have a hotdrop modifier? somebody should check that).
