I strongly sugest using the Aerial suport expedition on E2, It deals a decent amount on E2 pre-boss, spend quite less rscs(bauxite about 100 if you're not lucky you get an AACI on boss node tho), Load your best 4 CVs with 2 Dive bombers,2 Radars and your best 2 DDs with 1 gun + 2 radars, Pre-boss can make do with 4 CVLs to make it economic(only one that needs fully sparkling cause activation rate), Boss sparkling the 4 CVs is more than enough

The advantages

- Pretty Low on Ammo and Fuel(for a suport expedition that is)

- Can sometimes pull incredible damage on hard targets(got a run that oblitared the pinoquio imps)

- Spread damage lower the danger of closing torpedoes on pre-boss

- Incredible low morale cost(only 3 per sortie)

The Disadvantages

- Hard on bauxite

- Pinoquio Imps will AACI and you will bleed even more bauxite.

- Hard to equip since you need a LOT of surface radar(2 for each CV and DD)

- Can miss quite easily like Artillery one.
