@Mr. Nutt25: Maybe, though I'm trying to keep these following the current format of the Drill levels (Aircraft Carrier, Duel, Naval Battle, Maritime Fortress, Air Base, Night Battle). I'll continue making them with steadily increasing difficulty up until the final ones are a challenge for even super-warships. DocWeldin's Aircraft Carrier Lv4 would probably be pretty high up, maybe around four to five levels after Duel Lv13.
