The Canadian brigade was on 24 hour notice at all times, you had to have your ruck ready to go when ever there was an alert called, the alert was called "snowball" all the sirens on the base would go off and you would hear "snowball, snowball" over the loud speakers, You then got dressed and ran to your track vehicle, formed up and went to a hide to prepare for the Soviet invasion. Our job was to slow the Soviet advance until reinforcements would arrive and also to give time for all of the NATO country’s to mobiles. This was also was practiced every year on a fall exercise called “reforgerâ€; a whole US division would be transported to Germany. I was told that the Canadian Brigade was given a life expectancy of 24 hours.
