Fastest way to get a general?

Whats the fastest way to get a general in Halo wars? Its the only achivement im misssing in all of the games and it sucks to not be able to say “i have ALL of the halo achivements”

i could boost you if you would like ill get on in about an hour im xsubmachxhh

well not really boost but get points off of eachother

Death match is good.
