A military jury has found Major Daryl Watts not guilty of manslaughter and breach of duty in connection with a fatal training in Afghanistan that killed a soldier and injured four others.

However, Watts has been found guilty of lawfully causing bodily harm, and two counts of negligent performance of a military duty.

Cpl. Josh Baker died when a Claymore anti-personnel mine peppered the platoon on a practice range near Kandahar city in February 2010.

The Crown had argued Watts, who was the platoon commander, turned a blind eye to safety standards and abdicated his duty as a leader during the exercise.

The defence countered Watts had no training on the C-19, and handed over the responsibility for safety to his second-in-command, who was an expert on the weapon.
