Technology is ok as long as the people know how to use it - 'all the gear, and no idea!' springs to mind - but one side makes an advance in technology the others either copy or find a way of defeating said technology. And good intel needed too.
In Afghanistan expensive equipment, and irreplaceable lives, destroyed for the cost of some explosives and a mobile phone - v - high tech armament hitting the wrong building/compound/house! Or vice-versa!
