it's not quite that simple. tanks are easy to see - they are big, move
fairly straight lines, are made of metal and generally have rather hot
exhausts somewhere. thus, you can detect them with optics, radar or
infrared, or set tripwires, pressure sensors, etc, and be able to find
them well enough to hit with a rocket (tanks are also quite large).

people are not so easy to hit.	they don't show up on radar, and on
and millimetric radar are hard to distinguish from background - this is
the 'vision problem' of artificial intelligence research, and it's
near solved. you can probably pick people out in IR, but then you have
filter out other sources of heat, and you're back to the vision problem.
