So I was re-reading subjugation getting ready for fel to put out another chapter, and Jason's quote that he needed to:
"pull out the really weird shit and hit them with things they’d never seen before, keep them constantly off guard"
He can't just hit them when they are out in the open, he needs to drive them to build up in their bases for security. I think of the book "dune" where muadib (the young duke) talks about the tactics of a guerrilla war and gets the enemy to bunch up for safety, allowing him to move about more freely.
So I was thinking, what wierd shit could jason build?
1. How about little hovering robots that could infiltrate bases and sow confusion? Spider robots/hover robots that climb ceilings and air ducts to infiltrate Faey armories and spray armor disintigrating spray or plant hijackers in hovercars dropships or exomechs or plant explossives or set off ppg safety devices. Or, to make things funny. They could attach those magnetic devices like the ones that jason used to launch the hovercar 50 feet up in to the air, but without the field that stops them from exiting the autmosphere. We know that jason could sneak through ducts at the school to escape the faey, and "kate" could definitely explain to jason the faey's security defense works so that he could build around it.
2. Booby trap patrol lanes. The fay march along the boarders patrolling in hovercars and on foot. Make the patrol's hazardous would keep them off track. Automatic sprinkler systems that melt armor. Or take cutting tourches rigged to shoot larger cutter streams, say 5-10 feet long, alongside roads that simply cut off the legs/wheels/fusilage of vehicles traveling by.
3. Cloaked space mines. Hide them in the shadow of the moon so as it goes near the space gate it interrupts cargo traffic lanes.
4. Giant annealing beams, diffused annealing torches that would fuse material together or to the ground from distances away. Hit a field of containers with it, and they are all melted to each other and to the ground. Better yet, hit a bunch of faey fighters sitting on a tarmac with it, and they can't scramble after you when you steal a dropship.
5. create two robots:
one "a box of jokes" which just goes into faey towns and terrorizes the population by playing pranks. Melt hair, melt clothes. liquify the plasticrete of doors of the opera house and seal it shut with an audiance stuck inside. climb through the sewers under the city and sporadically launch a signal that causes the buildings to be magnifiers for the "itching" wave length. That type of thing. Pretty harmless but frustrating none the less, and could be used to cause a distraction so Jason can attack somewhere else.
Two "a jack in the box" which goes around with a supply of supper strong gravimetric magnets launching military hardware and non-spacial engine vehicles and containers into space. If its large and valuable to the faey, launch it into space and out of the atmosphere, just like the hovercar that went up 50 feet. Clutter up orbit with missilanious crap. All the better to hide space mines in with crap that should be anchored to the earth with gravity, choking the space lanes.
Anyway, just wierd funny shit that will make the faey say,"What the...!!!??"
