Thanks guys.
90% is where I am at right now, done with the L2A4. I noticed that my gunner often hits first, but that the T-80s are pretty hard to kill. If I stick around chasing the kill, by the time I kill one (after 2-3 shots, mostly accurate), I am taking accurate and damaging return fire. But I can only shoot-scoot so much, and I have the problem that I have to reacquire every time. And it seems that once alerted, the enemy is very good at engaging me when I pop up.
I need to work on keeping oriented to the ground, and realizing that the TC Peri points to the same bearing consistently, independent of turret movement.
How do I get the gunner to go "weapons free"? Currently if he says "on" when I don't see anything I give a fire order authorizing him to engage. But is there any way to get him to freely engage by target priority, while still retaining the freedom to override if I see something more pressing?
