The big picture in FFG's Squadron article shows the Lancer to have 3 hull, while the card lists 4............
Lancer Class Issue - 3 or 4 hull?
I noticed that as well, I have to assume the squadron card is correct, and the lineup photo is an outdated promo pic that didn't get corrected. 4 hull is already kind of pushing it. 3 hull would be not good enough at all.
TIE Fighter level hull strength would make absolutely no sense at all for the lancer.
It has to be 4...
Looks like a rendering error, since the stand is pointing at 4 and they all point at the maximum.
