Okay bumping this again.
You really need to adjust that infantry AI spotting. Right now its close to unplayable with infantry vs infantry, as soon as you get in contact you die as they spot you so much faster then you can spot them.
I have played SB since 2002 era and right now you are basicly back to how we used infantry in SB1, let them go first and get shot up and reveal the enemy and let vehicles shoot the dismounts, so useless they are right now.
