Modern warfare is moving to a 4th dimension (not in a physics sense).
Traditionally, most people only see 2 dimensions of a military, its attack and defence. An M1 Tank can kill a T-90 at x range and can defeat n type warhead with its armor.
What people never factor in is the third dimension, mobility. The M1 can kill a T-90 because it can manuever itself into a position where the T-90 can't respond.
With information technology, we are moving into a 4th dimension. The M1 can kill a T-90 because it knows where it is relative to its environent and pin point a location that the T-90 can't respond rapidly. The M1 can then manuever itself into that position and use its gun to kill the T-90.
Things like mobility and information dominance are intangible and contribute a much greater combat power than attack and defence alone. This is the reason why a Carrier battle group is so effective.
