Here is my main battlegroup used by my army. I hardly ever go into battle without it. It includes 4 Tiger Light Tanks, 3 Puma Heavy Assualt Tanks, 2 Leopard Heavy Artillery Units and 2 Lion Superheavy Units.
Nice work jack, your the first one with a battlegroup lol. Only thing is that your color reference boxes need to differ from unit to unit, it's not a class oriented thing but wrather a way to link the profile card to a unit. Your unit will have a plate underneath of it called a "placer block" which will act as a reference to movement and range, and it should also be colored to match the color in the profile card's color box for that unit, i that makes any sense.
