Highly recommended.
Some clever dude shared a highly effective strategy recently... Use attack choppers as the core of your MP army, backed up with tac helos for repairs/support... I add a couple of heavy tanks and 2-3 APCs to that... You can clear out most bases lower than your own level... Attack choppers take down defenses from range. Heavy tanks suck up incoming fire but get healed by the tac helos. Meanwhile your APCs can sit back out of harms way, throwing infantry into the fight...
Great for racking up wins/resources/NTGs in MP games... Just pick a medal level low enough for this to work...
Wait! Wasn't the attack chopper thing your idea, Wrathchild?!?! It's still genius...
