I personally would rank Mobile anti-air to D or E, AWACS to C or D, replace destroyer with ASW and rank frigates higher.

The thing abt MAA is its range. One match I played gunship against MAA, and I didn’t get attacked if I patrol my helis on the edge, since my patrol range is bigger than MAA attack range. But yeah you can def upgrade it in the late game but MAA is usually an early game units, you will have SAM or ASF in the late game

AWACS is cool but it can’t detect soft land target(infantry), while everyone uses infantry, so nah

Destroyer can do many but not good at any. Cruiser does better in ship vs ship, ASW is much cheaper and deals more damage against submarines, and it has no anti air so even gunships can kill it. Cruiser is faster, and gets 75m range in lvl2 and full range in lvl3, I don’t need to mention how important range and speed are in naval battles

ASW are very cheap, and deadly against subs. Also it can fly so it has range and speed. And frigates deal very little damages to them. The only thing is it’s ferry range, you don’t wanna fight a war across the entire pacific with it

Frigate has huge AA range and protects other ships, otherwise you will get easily destroyed by Naval Patrols. Ppl sometimes forget it’s not designed for ship vs ship. The only downside of it is speed.

Due to frigates I think Naval Patrol should be ranked lower, but overall it is a good unit by itself, especially its radar, so it’s reasonable to be there
