The headline pretty much says it all as the Washington Times reports the details.  American supplied arms can’t be tracked because of multiple errors in the two systems used to track them.  Besides the concern that four of ten weapons may be unaccounted for and in the hands of the black market or the enemy, the government is considering how to decrease the number of weapons available as we withdraw.  The key assumption is there will be less need after we are gone.

Sometimes it’s easy to see how errors get into the system in the first place.
