They want you to buy four of them, then they’ll make a points adjustment. I’m only getting 1, maybe 2. I already have 3 and the dials are the same as the rebel dial. I’ll just be putting them in the dual upgrade kit so you can’t tell the difference.
Or a Corps unit that requires a Veteran to be in the army list to be included, which might be why FFG called it a "Detachment" a couple of times in the article. Which would also explain the higher price if they can be used as part of the requirements for Corps units.
I'm guessing the extra plastic meant FFG decided to increase the price to keep their minimum profits. There may also have been a slight increase in packaging costs due to having to include two different bases (depending on if the packaging is automated or done by hand).
