Mangala Samarakoon

He competed at the 2012 Summer Olympics representing Sri Lanka in the men's 10 metre air rifle and men's 50 metre rifle prone which was also his maiden Olympic appearance. He failed to advance in both. Samarakoon also represented Sri Lanka at the 2016 Summer Olympics which was held in Rio de Janeiro. During the 2016 Summer Olympics, he blamed the Sri Lanka Shooting Sports Federation for failing to provide him a suitable shooting kit which made his participation quite difficult when he was slotted to compete in the men's 10m air rifle event. He was settled only for 50th position in the men's 10m air rifle event during the Rio Olympics.

After taking the sport of shooting in 2001, he began competing in several international competitions including the South Asian Games, Asian Games, Commonwealth Games and the Olympics. He made his mark in the sport of shooting after claiming a gold medal in the men's 50m rifle prone event during the 2006 South Asian Games. He also went onto represent Sri Lanka at the 2006 Asian Games, 2010 Asian Games, 2010 Commonwealth Games, 2012 Summer Olympics, 2014 Commonwealth Games, 2016 South Asian Games, 2016 Summer Olympics and 2019 South Asian Games.

After completing his primary and secondary education at the Madawala Maha Vidyalaya, Mangala joined Sri Lanka Army on 18 January 2000 initially to pursue his training in athletics. However, he soon switched to the sport of shooting a year later after being spotted for his talent for shooting during military training. He was also coached by former veteran sport shooter Pushpamali Ramanayake for several years.
