Amos has served in the Singapore Police Force for 17 years. As the former Assistant Superintendent of Police (ASP NS), he carried out duties at the OC Unit of Alpha KINS 7. Amos was trained in weapons handling and formulation of ground protection plans, which helped in the defence of multiple key installations.

Under his leadership, the OC Unit of Alpha KINS 7 was awarded the ‘Best Deployed Unit’ and ‘Best Operational Unit’ in 2006. In 2007, the unit was again awarded the ‘Best Deployed Unit’, thereby retaining the title consecutively for 2 years.

Apart from having experience in high-level executive protection, Amos is also a certified instructor who can train and teach martial arts of the Israeli Special Forces.  Some of those martial arts skills include hand-to-hand combat, controlling and restraining methods, defence against knife attacks and weapon disarming techniques (knife and handguns). Last but not least, he is proficient in Wing Chun and Taekwondo.

With these credentials, expertise and professionalism, Amos heads SRS in providing the highest quality security services for all clients.
