A lone arty gun is not a sitting duck!
PLEASE…
Artillery is WORTHLESS in the face of an armor breakthrough.
There is a reason that guys who shot artillery in Afghanistan, got busted for wearing flip flops and hawaiin shirts, instead of combat uniform.
That said, the whole concept of an “army” is lost in Axis and Allies. Usually an “Army” consists of a multitude of different groups, many times including but not exclusive to artillery, tanks, scout vehicles, etc etc.
Much like how a transport flotilla, isn’t just transports.
I begrudgingly have to agree that the single piece doesn’t JUST represent artillery. BUT, I would love to see a rule, where if an Army group LOSES it’s infantry cover, that for a round, the artillery are at a disadvantage!
