Unit AI is so problematic

[mie001]

It's so annoying when you don't have some basic control like passive mode or evasive mode. I lost my gd mind in GDF 8th mission when I try to rush base building while stop those fking escort unit from blowing off the scan tower I aim to capture for base defense. Not to mention they tend to stay put if targeted by outrange fire, which you need to manage by yourself
I can't take it anymore, why can't you set unit to passive mode, are they all trigger happy murder or something?
