Science magazine recently featured the effect that a roll of sticky tape generates x rays when detached at a vacuum
The article noted 100 mW from about a 1mm deep 30mm wide sticky tape thus just ten times that area generates a watt
Two sheets of office paper covered with sticky tape goop then rapidly
separated at a vacuum produce near 254 times 200 around 5,000 watts
take two frisbees made from metal or graphite coat with sticky tape goo Then put just a little plastic explosive or possibly even a cartidge between the sides ):) goes to )<<<boom>>>) on contact with a tank
aim the frisbee at the preferred part of the tank
I think 10,000 Watts of high energy photons near the tanks electronics will errorify and or wipe them out This is like an EMP effect yet different as inches or feet of metal shielding is penetrable
fortunately for the humans the dose may be survivable I have also read that a variant of melatonin with a big hydrocarbon group on it gives mammals seven times the usual radiation resistance
anyway ten dollar photon torpedo takes out multimillion dollar tank
