The same as Atomic, except 50% or so less effective. Go Atomic for the extra 3 planes (and all the other good things) ASAP if you can.
As some stated, the bazooka/commando combination (say, 12 or so commandos and the rest bazookas) is by far the most effective today at this Age (Global/Atomic/CW). It's been this way for over a year now, so likely won't be for another year as the game changes... but it's worth learning and using today. There are a lot of videos about this combination; you'll find them. Don't specify "Global" in your search, though, and few (if any) post Global videos.
