This kind soldier was seen sheltering an old man from the heavy downpour on Monday.
Rain began to pelt down on 78-year-old Pargan Singh while he was waiting for a taxi to take him to Changi General Hospital.
The retiree suffered a stroke 15 years ago which impaired his movement and affected his speech.
It was drizzling when he left his Bedok North home, and he thought the rain would pass rather than turn into a thunderstorm.
Mr Christopher Ang waited with Mr Singh for twenty minutes until a free taxi was available, before heading off to drive his own vehicle in a nearby carpark.
