i think technology like this is bad for militaries, it makes soldiers so heavyily reliant on them that in the end it makes them careless.
think of it this way, say a small child is to learn math (multiplication, division.....) but instead of teaching him the mathematical rules he is given a calculator and just told what buttons to push. now after a while he\'s a master at using the calc. then suddenly the batteries die out, once that happens the kid is lost, he cannot solve anything even the simplest of calculations.
in short a little technology is good, too much and it can be harmful.
