1. Why was the Achilles selected?
The Lords of the Night commander had a lot of Economic Points (EPs, which our the ingame currency we use) saved up. Instead of spending ~200 EP on 2-3 AFS and green pilots (5/6), she opted to get a ~450 EP Avenger Assault Dropship, that comes standard with a regular crew (4/5). Part of this was to create large thread to draw fire from the Mules, which would easily be destroyed if the enemy could avoid our own ASF screens. They could attempt to avoid the Avenger, but at their own peril.
2. How many maps did you guys use to play the scenario?
We used 4 aerospace map sheets, and had all units with a starting thrust of 6. If we had higher thrust, we probably would have started using rolling mapsheets.
3. If you were going to expand your Aero-Assets would you opt for heavier fighters?
I actually expanded my ASF assets between Texlos and Warlock. I added 3 Cheetah F-13s (but I stripped out the ERSL for more armor). Speed is very important for ASFs. In ground attack situations, ASFs moving 10/15 or higher can actual move two abstract map hexes per turn, allowing them to strike or strafe every turn, as well as out maneuver slower bird in dogfights over the ground.
The dogfighting rules are as thus, roll a pilot check, if you succeed, add half you safe thrust to the roll, then compare to the opponent. If you win, you dictate range. If you with by like 5+, you get behind them and dictate range. Pretty easy to see why light fighters are pretty darn good.
Also, in pretty much every mission we've used ASFs, at least one has crashed n' burned. And since they cannot be salvaged, lighter fighters are pretty cheap and replacable. Additionally, since we're working with the CCAF, Transgressors are pretty much the heaviest ASF we have regular access to. Other request would require acquisition rolls to see if you can find them on the market, making replacements hard to come by. The Troika might be a good option for someone looking to add more fire support, but since we're most often we're using our ASFs for ground missions, they aren't really great for that.
Personally, as the commander of the Piotrowski's Predators, I've pretty much got my unit to the size I'd like. Now I'm going to focus on getting some more defensible dropships. I'm too scared to leave my stuff in these Mules. It only takes a handful of Arrow Air to Air to pop one like a balloon and lose some of your stuff.
