SHILO, Man. -- The family of a reservist who died on a military base in Manitoba says Pte. Kirby Tott felt privileged to serve his country.

Tott, who was 25, died Saturday while learning to reinforce a trench at Canadian Forces Base Shilo.

The military says Tott suddenly collapsed and there were no vehicles or equipment involved.

An autopsy is underway to determine the cause of death.

Tott was a corrections officer from Prince George, B.C., who belonged to a reserve regiment called the Rocky Mountain Rangers.

In a statement issued through the military, his family says Tott was driven to help others.

"Kirby was loved by his family and friends alike -- he always brought a smile to our faces and our hearts," the statement read.

"He enrolled in the military because of his natural need to help others. After completing his time in the army he intended to apply for the RCMP.

"Our family would like to recognize and thank the community for their generous outpouring of sympathy since we received the news of his tragic passing -- we have felt very loved and supported during this trying time."
