Taking out armor, do I have my bases covered?

[White Eagle]

Upon having my first tank vs tank exchanges I was expecting the battles to go very fast, 1 or 2 rounds fired and a kill but I have found that in Red Victory that some exchanges can go back and forth with each tank firing 6-12 rounds. I am guessing some manuver or something else is abstracted into the combat results tables that is lessening the "to hit" odds.

So I have come up with my own personal list of things to do to maximize my chances of a hit, please let me know if I am missing anything.

-Use AP ammo
-Fire at 1/2 the max range or less
-Avoid front armor shots, armor is 150% value right?
-Vehicles dont recover status, but effectiveness is figured in right? The higer the status the better for me to score a hit.

I had poor luck with Panzerfaust's, but I use the same principle and have gotten a few kills.

-Fire at range of 1 instead of max range of 2
-Assaults with Panzerfausts don't work for me, the whole team gets wiped out or hurt pretty bad, so I stay at range of 1 when attacking.
-I try to keep my team free of any "pinned" or other states
- Try to use against side or rear armor.
-Does the "ground" mode affect Panzerfausts hits?

Ok, so that's what I am doing but I am still finding myself sometimes going through 12 shots of a panserfaust to get a kill. From my list is there anything I am missing?

Thanks for looking it over, any veteran tips/help is appreciated!
