Thank you for the extensive feedback, appreciate the time you took to write out your thoughts.
Tutorial 4: Yeah there's a pretty unfair jump in difficulty for a tutorial, I'll adjust the difficulty. The first group of enemies shouldn't immediately attack and that will be fixed.
I kept the tank as I do want the focus to stay on armored warfare, especially when IFVs and infantry can be fragile and unpredictably wiped out in seconds, but the balance of infantry will definitely be worked on.
I really like the point about demonstrating ambush and defensive potential, gonna see if I can work that into the tutorial. Also thanks for voicing your thoughts on the armory angle.
M is a dev command haha, good catch! will fix that.
