Drones are cheap early game air units which pack a punch when in numbers, but can be hit by any ground unit
Fighters fire at both ground and air targets (AA ammo is limited), while Gunships can only attack ground targets
Bombers are outstanding against structures, and very good against defenses - even missile defenses!
Fighter and Gunship missiles are excellent vs vehicles
Fighter and Gunship bullets are great vs bots
Bombers and some fighters require available AirPads to be built
Air plants (factories) already have two airpad slots in them
Check the “PlaneCap” UI indicator, next to the commander counter
The "plane freeze" ability allows you to halt mid-air a flying bomber (set to "Fly" mode)
To use it, click on a destination (to move) and then click Stop (S key shortcut)
Unit(s) will turn around to aim at the destination(s) and grind to a halt, then hover on the spot
Practice it to, for instance, make tight curves with your fighters and easily group bombers to make sure they reach their target at the same time
Air-to-ground Missiles are excellent vs Bombers
Flak & Laser weapons don’t do so great vs them
Air-to-ground Flak shells (from, eg. Claw) are great vs Fighters
Missiles are only okay vs fighters, especially due to the fighters speed
Gunships are vulnerable to (especially) Missiles and Flak damage types
Gunships and bombers are very vulnerable to fighters
The Krow (Kern’s Tier 5 Gunship) is very resilient and fires at both air and ground
Lamina (Blow’s Tier 3 Gunship) is not super resistant but moves fast and fires cannon shells at ground targets, being a great Avatar-assassin and hard to stop with mobile AA flak vehicles
Besides stationary AA towers, use fighters against laminas (or any other gunship, for the matter)
