I'm just curious, like which ones?
Being new and trying to get a plane off the ground in WW2 online is a real chore if you do not go through the tutorial.
even their old tutorial can get you in the air fairly quickly
https://www.youtube.com/watch?v=wyrr1p9lBSUMy druthers are mainly Infantry and some Armor, haven't spent much flight time, but I rarely flew in AH either.
The Armor is like it used to be in AH, using multiple crew positions and
having to change gears manually.
Biggest difference is the full tutorial on weapons/equipment use, movement and map use. If you don't utilize the tutorials and you're a newbie, the learning curve is way out there.
