Reservists from the Victoria Park armouries in Sydney begin a training exercise today that will run until Sunday.
The exercise is separate from another military training operation based out of Open Hearth Park in Sydney.
The 36 Service Battalion will be training near Victoria Park, as well as in Glace Bay, North Sydney and Louisbourg.
The military says people will see increased military activity in those areas as well as military vehicles on area roads during the exercise.
