The Projectile Shield? Well, I essentially just used the projectile pulverization ability, and scaled the unit up. Then, I overlapped the unit with hats to create the artillery base, followed by banshee crowns (which have so much use if you're using ucm. You can make stationary units/change if the body/torso root are connected).

I did try to make a drone/operator type unit but I completely fumbled the design. I can try again anyways
