The PMG comprised approx. 100 personnel, was unarmed and wore bright yellow shirts and hats. It had no specific legal power although it did have a mandate under the Lincoln Agreement. It remained definitively neutral at all times. In the early stages of its deployment, it acted primarily as a ceasefire monitoring group and spread information about developments in the peace process. Following the Bougainville Peace Agreement, the PMG focused primarily on facilitating the weapons disposal program, in co-operation with the small UN Observer Mission on Bougainville (UNOMB). There was also some logistical support given to the constitutional consultation and drafting process from 2003.
