For his performance in the role, he was awarded the Conspicuous Service Cross in the 1995 Birthday Honours.[7] Sengelman assumed command of the 4th Battalion, Royal Australian Regiment (Commando) (4RAR) in January 2000.[8] 4RAR had not long come through a complete restructure to transition from a light infantry battalion to a commando special forces unit in order to supplement the capability of the SASR.[9] Three months into Sengelman's command, however, 4RAR was tasked to deploy with the United Nations Transitional Administration in East Timor and had to be rapidly reorganised as light infantry to meet its operational requirements. Sengelman led 4RAR in East Timor from April to October 2000, working with the East Timorese to ensure local security, gather intelligence and conduct regular patrols.[10] Sengelman relinquished command of 4RAR in Sydney in December 2001,[8] but in recognition of his "distinguished command and leadership" on operations in East Timor he was awarded the Distinguished Service Cross in the 2002 Birthday Honours.[11]
