Explosion and fire at Canadian military base caused by grenade launcher exercise

A training exercise with grenade launchers at a Canadian military base led to an explosion and fire, resulting in the deaths of four soldiers. The incident occurred during routine military training at the Wainwright base, where troops were using the C-16 grenade launcher. Firefighters were unable to access the blaze due to the area being marked as permanently dangerous, potentially containing unexploded ordnance. The fire spread rapidly, trapping many soldiers, with 27 hospitalized, 13 in critical condition. Investigations are underway, and this incident is considered one of the worst in Canadian military history.
