Mohammad bin Haji Daud (born 1 May 1943) is a Bruneian aristocrat, diplomat, politician, and military officer who served as the first commander of the Royal Brunei Armed Forces (RBAF) from 1985 to 1990.

[2] In early December 1960, a radio station and the local newspaper announced a two-year officer cadet training opportunity at the Federation Military College (FMC) in Malaya.

By mid-December, 17 cadets who had applied for the programme underwent a selection process at the Sultan Omar Ali Saifuddien College gymnasium in Tasek Lama, where they were interviewed by a panel of four officers from the Malayan armed forces.

By 4 November 1961, as part of the Malayan armed forces, the cadets were temporarily assigned to a battalion in Mentakab, Pahang, and Pengkalan Chepa, Kelantan, where they gained practical experience and further honed their skills.

[3] On 8 December 1962, Mohammad was among the three musketeers to be commissioned as a second lieutenant by Sultan Omar Ali Saifuddien III, in a ceremony presided over by the Yang di-Pertuan Agong of Malaya, Putra of Perlis.

During his time at the FMC, Mohammad underwent training in infantry tactics, jungle warfare, public order management, and ceremonial duties, all of which equipped him for a future leadership role in the armed forces.

The RBAF arsenal includes field artillery, Rapier surface-to-air missiles, Bell 212 helicopters, fast patrol craft, and FV101 Scorpion tanks.

[13] After spending a year at the Royal College of Defence Studies in London in 1985,[2] Brigadier General Mohammad was appointed as the first local commander of the RBAF on 31 December 1985.

Following the death of Omar Ali in September 1986, Sultan Hassanal Bolkiah assumed the defence portfolio and restructured the RBAF, promoting Mohammad to the rank of major general and appointing him as Chief of the Armed Forces Staff.

In order to leverage Brunei's strategic location and the expanding worldwide container shipping sector, BEDB re-engaged Halcrow Group to help market and promote Pulau Muara Besar as a globally competitive port.

[18][19] On 22 June 2005, he launched the Projek Memeduli Warga Emas, focusing on the welfare of less fortunate senior citizens and emphasising the role of volunteers, the community, and family in addressing their needs.

[25] On 13 February 2007, Mohammad attended the opening of the B$24 million Muara jetty, a key infrastructure project set to support Brunei Shell Petroleum's offshore operations for the next three decades.

He highlighted the importance of leveraging mobile phones and new media to engage younger audiences and advocated for collaboration with telecom companies to distribute ASEAN-related content.

[38] Additionally, on 10 August 2020, Mohammad, alongside Pengiran Ibnu Basit, officiated the launch of the upgraded Kowira Minimart at Berakas Garrison, marking another milestone in his ongoing contributions to his community and country.

[2] Mohammad was honoured by Sultan Hassanal Bolkiah with the manteri title of Pehin Orang Kaya Seri Dewa, bearing the style Yang Dimuliakan.
