Mortar Quads are great against slow tanks, they can also outrange NuWa Cannons, if you play against them. If you have economy for that, you can even use Drakuvs to catch some slower tanks and destroy them with Mortar Quads. Or catch any unfortunate T1-T2 tank and snipe it with Morales for some captured units you would find useful (especially IFVs).
Catastrophes are your standard brute force tanks (understand old Apocalypse/current Abrams), that have potent AA weapon when in a pinch. But remember to make full use of those firing ports they have. Desolators for anti ground forces, Pyro for that extra structure damage.
With Fury Drones, you have to ask yourself one question. "Do I have the capabilities and time to micro disposable units?" If yes, then enjoy these glorified Crazy Ivan bombs, that need to be deployed first to use with range of 9 and huge damage potential, especially against structures. But beware of cannon-fodder units, as Fury Drones are a bit more expensive than Terror Drones (and one use only).
I have one funny operation with Vultures, especially with more than 3. Although it's more effective against structures with more cells. And do not try that near any AA, as you would waste 5000+ credits for some gimmick. So, you select a group of Vultures and sent them over enemy structure with Alt. they will hover above it. Then you deploy them. enjoy the burst with flame aftermath.
And from my experience, majority of defenses and smaller structures cannot survive 2 napalm bombs from Arsonist. Do not forget to disguise him first. Enjoy
Yeah, I like Bomb Buggies.
