I doesnīt looks like a board game and as far as i researched for review it hasnīt be a board game... How we get to think that it was maybe a board game???
About tanks and artillery, no the armor units or other vehicles got amor and anti-tank strenght as place of attack and defence, the infantry got 1 or nothing for these values.
Anyway you are right, artillery (field artillery like anti-tank cannos or AA guns and heavy support artillery like howitzers or mortars) are boths very unrated, only rocket artillery does some real damage and i donīt like the way for use support artillery inside the game.
The best way to defeat the enemy its to cut their supplies. So donīt try to bull units, encircle them or try to destroy enemies HQ and got them cutted off. If you encircle an enemy unit wirh low supply, they will surrender.
