By the way, 2 things I would like to add
:
1. About counter battery ability of the cancer regiment: When activated, use the "stop auto fire" command of your mortars (in case you have one) Counter battery requires much munition after June 21st Patch... if you react quick, it is a great munition loss for your opponent, besides that he needs to deactivate the ability in case he want's to produce units or use his HQ howitzers active (with flare mark target)
2. If your inf, especially your pzgrens, meet an activated bofors, push the retreat button after they fired their first rocket/ after the bofors opened fire
Never wait until only 1 or 2 men of the squad are left
