Who detects whom?
The Taliban (and other guerilla groups) have demonstrated their willingness to adopt new technology, as well as their ability to incorporate it into their tactics and strategy.
If each US soldier is electronically tagged, it will make it easier for their opponents to attack them (e.g. IEDs with tag-detectors).
Also, it will assist the guerillas in gathering information on the movement of US forces and planning accordingly.
Furthermore, US forces will realise this and morale will be severely weakened. Knowing that the enemy knows exactly where you are, what you are doing and (probably) where you are going, while you can't see them, will sap any soldier's motivation. Additionally, the demonstrated inability of the central command to make sensible strategic decisions will aggravate the situation.
Surely the Pentagon must have taken this into consideration, but I cannot imagine how they would turn such a vulnerability to their advantage in the long run.
The above comments are made under the assumption that the Pentagon wants to conclude combat operations as soon as possible so that a step can be taken toward the end of the War on Terror.
