Who came up with that idea? crazy implementations

People, still on the tracked vs wheels, I cam across the M1128 Gun system:

Crew amenities
Because the vehicle was designed without air conditioning, crews are given individual cooling vests that circulate cooled water from outside the vehicle to the garment. IV fluids can also be provided. Vehicle computers still overheat regularly.[3]

WHAT?? Even I can see that this is a bit off-centre!

Any other just as bizarre ideas?
