A military vehicle involved with Exercise Arctic Ram, taking place later this month in the Northwest Territories, turned over on Highway 3 Friday near Behchoko.

The five-tonne vehicle called a "reefer" was carrying supplies, including snowmobiles that were to be used in the army exercise.

One soldier was sent to Stanton Territorial Hospital with undetermined injuries.

Approximately 100 litres of oil spilled onto the ground.

The RCMP is investigating what caused the accident.
