Operationally ready national servicemen (NSmen) typically attend in-camp training every year for a period of 10 years, but SingTel associate director Mohammed Nurizham Shah Abdullah is already in his 15th year of national service.

The father of four spends an average of two days a month serving as NS Deputy Commander of Public Transport Security Command (Transcom), a police command set up in 2009 to guard Singapore's public transport network against criminals and terrorists.

The 40-year-old, who oversees about 800 NSmen at Transcom, was among 10 men who received the Home Team NSman of the Year award at this year's Home Team National Service Awards presentation ceremony held at the Grand Copthorne Waterfront Hotel yesterday evening.

"I'm quite fortunate because I've been able to explain to my supervisors at work about the significance of my NS duties. So, I've been able to manage these duties with the support of my bosses and my wife," he said. "Working closely with the young men in our division keeps me feeling young and I get to encourage them to view their in-camp training positively," he added.

The 10 men were honoured for the professionalism and dedication to their NS duties, Deputy Prime Minister and Home Affairs Minister Teo Chee Hean said in a speech at the ceremony.

"Full-time national servicemen and NSmen are an integral part of the Home Team. Over time, many of them have taken on larger responsibilities and risen to senior positions," said DPM Teo.

These include police NSmen who have taken charge of police security operations at the annual Geylang Serai Bazaar and Singapore Civil Defence Force (SCDF) NSmen, more of whom are being included in the SCDF's overseas contingent called Operation Lionheart, which provides humanitarian aid to disaster-hit countries.

At last night's ceremony, 70 employers also received awards for their strong support of employees who undergo national service. Three of them - the People's Association, Millennia Institute and the National University of Singapore - were inducted into the Minister's Honour Roll, which recognises the top employers for their exemplary support of their NSmen.
