Consider this.
We have hundreds of prisoners from this operation.

With this pack of pigs the alternative will ALWAYS be the same, so there is no difference. The idea of chips has been brought up before and I am sure that most of the troops would not object considering the possible benefits. If the chips were in place, it might have been possible to track them within hours.
