Soldiers from the London area are training in Lambton Shores this weekend.
The Canadian Armed Forces said about 75 members of its reserve unit are conducting a winter warfare exercise in the Thedford area Friday until Sunday.
Captain Joshua MacAulay said they'll be testing practical skills around residential areas and farmland.
"Things like snaring, land navigation, surviving in cold weather environments," said MacAulay. "We have qualified instructors who are supervising all of the training and the Thedford area proved to be a good spot with its open fields. They can do maneuvers quite easily without being tangled up in the branches or a forest."
MacAulay said while most of the activities will happen during daylight hours, there will be some scenarios executed at night.
Residents may see military vehicles and personnel participating in exercises with unloaded weapons.
He said certain areas may be inaccessible during the exercises, but there will be no firing of any ammunition.
Members of the public are asked to take extra caution when approaching any military vehicles in the area.
