not sure if anyone found yourself in situation like mine.
I played a battle 3 vs 3 on hard, only me is human, all other are AI. As normal I build up my forces and go however, the opposing AI massing their arty and keep pounding my rally point so I have no choice but to race and crush those arty fast. As I raced, the rest of opposing AI came to reinforce that AI so I found myself facing superior forces 3:1 however, I have 2 AIs on my side supposed to be my allies. They have massive army (all prototype [mobile AA + superheavy tank) but they did nothing other than massing their army at the river even though the opposing bases are now defenceless because they are battling me. I am facing the odds, I am trying my best to repel the aggressors, then all the opposing AI pushed my forces back to my bases, on the left side, I am facing Advanced Heavy Tanks, superheavy tanks, on the right side, assault guns keep pounding my administrative buildings and infantry infiltrated my bases through forest. Still my other AI allies would just rather to massing their armies at their bases (even though it is massive and strong armies) instead sending their forces to rescue me. There is nothing I can do, I have worst allies in my history of commanding armies in ruse.
At another occasion, I played 2vs 2 Hard, again only me is human, This time, I had a dumb AI ally, it using assault guns to fend of tanks heavy tanks (result already obvious isnt) so I have to race my flak88 and constant dropping paras to rescue that dumb AI. luckily, this time, opposing tanks keep being ambushed by my paras so the Opposing AIs had to give up. Later on this dumb AI send army to help me crush enemies even though most of the time, I have to race my forces east to reinforce this dumb AI and race back to the west to fend off assault forces heading to my bases.
