Co-Op is not the walkover it used to be, the bots are getting better

Had a battle last night, there were 7 real players in Co-Op opt in, I was in a M113, ended up with 9 kills and 11975 damage and we still lost as I ran out of shells with the T-72 having 685 HP left, there was a stage in the game where it was 6 bots to 1, but I mamaged to whittle them down to the last one.
