Good point. I suppose it is ineveitable that our technology would fall into enemy hands.
There is already a method of detecting US military uniforms (to protect our soldiers from friendly fire). We are so much more technologically advanced I wish it helped us more.
Nonsense. A common credit or debit card has a specific account number.
There should be no possible way for the enemy...especially an enemy with no familiarity to indoor plumbing...to break the code within a reasonable short period of time in which our military could mount a rescue, recovery, or at the very minimum engage the enemy.
