Spot 70 Torpedoes - Best to be done with a cruiser with Hydro Acoustic and torpedoes as you'll probably have an exact opposite on the bot team.
In 7 battles, join the top 5 in your team by experience received - Top 5? Not hard at all.
Earn 100,000 XP - Just be productive and put on those EXP flags
Cause 1,500,000 HP of damage to ships - Not hard at all to achieve in one week
Destroyers - Get 72 "spotted" or "destroyed" ribbons - Probably the most challenging in this round. Get a fast DD and boost in to get those early "spotted" ribbons, then go for the kill.
Cruisers - Get 85 "spotted", "hits to citadel", or "set of fire" ribbons - Fire would be the best bet for this round, citadels second. Check your ships with 152mm or higher for their fire %.
Battleships - Get 700 main battery hits - 100 hits a day. It's slow but it can be done.
Carriers - Get 360 Rocket hits. - Look over your carriers and see who carries the most rockets per plane / per flight. Aim for cruisers and/or battleships
