Simply fill one of the lower legs of the platfrom with
mercury, and a little high explosives. Have a panic button in the ops
center. The SAS lands, and 1000 gallons of pure mercury are blasted
out into the channel. That wouldn't be nice.
Plays heck with your mercury delay line memory :-)
Also, while pure mercury is bad stuff, it's not as dangerous as
mercury compounds, such as organics or the oxide,
or lots of other stuff. Similarly, you could store toxic waste,
making your self-defense system a profit-making business...
But if you explicitly dump the waste yourself, not only
are you harming a bunch of non-participants in your fight,
you've got a liability problem that exceeds any profits you may have made.
Ain't worth it.
If the SAS are coming through the front door, you just went bankrupt.
If England, France, Belgium etc. *new* that you would dump a
massively toxic witches brew into their fishing waters, they might
make sure that you weren't invaded by guys with guns.
Then again, they just may shoot your off-site personel in
their sleep, and blockade your platform until you starve.
