The US Department of Defence (DoD) in October ordered a rotation of servicemen serving in the Gulf. The procedure will see a total decrease in the number of US personnel serving to an estimated 105,000 from a present total of about 130,000. The DoD on 6 November started alerting some of 43,000 US military reservists and National Guard troops for the possibility of mobilisation as part of the rotation (MEED 6:11:03).
