Never Start A Land War In Asia.
So, you want me to make a battleplan to deal with the four, well, eight, Monsters.
Here's the plan.
Forget the troops. Seriously. Now. We don't need anything that touches the ground here, and the fighter jocks and the gunners can probably stay in their bunks too.
Here's what is actually needed:
The Clan's fleet and the Scouttrooper Biker Scouts of the planetary garrisions. They don't touch the ground!
Plus whatever homing beacons are at hand, though wildlife trackers for scientific purposes would be preferable. Small, barely noticable, long range, and designed to attach to life forms. Depending on the local commander, maybe a few fighters or bombers capable of dropping ordinance, more on that in the recommendations.
Phase One:
The Biker Scouts will use speed and hit-and-run tactics to attach the active trackers and beacons onto the Monsters. Or get them into them. Organic glue, harpoons, getting eaten with them, I honestly don't care, either variant is valid.
Phase Two:
The fleet weeds out the trackers that didn't make it, then locks onto the beacons that did and uses them for tractor beam locks. Star Destroyers and most other capital ships can operate close to planetary surfaces. And then they lift those beasties off the damn planet.
For extra effect, do it at night and illuminated by spotlights. Abduct them like the aliens in the legends of old abducted humanoids - and we're the ones doing the probing! Insult to injury.
This will work!
A tractor beam is not a magnet, it is a force field. Force fields can hold organics. And no matter how big these things get: A Star Destroyer has significantly more mass and engine power. It'll pluck it's target like you pick daisies.
Phase Three:
The hard part. You have to decide what to do now. Options include:
-shooting the Monsters to pieces in mid-air and clear view for public morale
-dragging them up into space to suffocate
-dropping them from great heights alongside a pot of flowers, letting them contemplate life
-put them into an isolated arena and have them fight each other to the death, televize the event, then sell plushies.
Potential problems and recommendations:
-Judecca Abyssal: none, thanks to it being stupid enough to march inland far away from greater water bodies. Star Destroyer recommended. Dark Paladin for PR effect.
-Antenora Sandworm: might try to dig in if he notices the starship. The local commander might want to douse it in water or superglue by aircraft while the trackers are attached to increase drag with the sand and immobilize it. Star Destroyer recommended. Make it the Warspite if you want to be precise.
-Forest Beasts of Ptolomea: have to be plucked at the same time to minimize their potential to develop countertactics, but they have less mass than the other Monsters, probably on par with a large starfighter or light freighter. Cruisers and even Frigates and Corvettes should be able to handle. Precise tractor targeting should not be an issue from directly overhead. Killing them piecemeal might also dumb the hive mind down, it's the local commander's call. They may also try to pile up in one tractor beam to overwhelm a single ship, but that will make them easy prey for the ship's guns. Assign the Corellian Gunboats.
-Caina Colossus: just douse the area around it in fuel or low-intensity laser fire to deny it access and quick production of ice. Might even drown in the molten water. Star Destroyer recommended, Indomitable.
-General recommendation: have the ships approach from directly overhead while the Biker Scouts draw the attention to the ground level. Adds an element of surprise.
-All other troops not assigned to this mission can just do their thing, protecting civilians and cleansing cities. Maybe go in the direction the low-tier monsters come from and blow up their lairs, I really don't care.
So why is this the best plan?
-projected casualties are within the low two-digit range.
-it allows for the use of the imperial symbols of power, the Star Destroyers.
-it shows the Empire's iron fist and will to use it on it's enemies without hesitation.
And that's how a pirate in bathrobe and Darth Vader plush slippers makes your problems disappear, quick and cheap.
