Let's keep our history straight here. The 25th Bde was raised for service in Korea and was sent to Ft Lewis,WA in the fall of 1950 for pre-deployment training. The reason for this was the season of the year and the fact that suitable ,warmer weather training area was available in the US. The Bde deployed directly to Korea on completion of training in Ft Lewis.
The 25th Bde was equipped with standard Cdn/UKsmall arms throughout as it operated in Korea under first the Commonwealth Bde,then the Commonwealth Div. Members of the Cdn units did use a variety of US small arms in Korea,but only on an unofficial basis as they were "aquired" by individual soldiers.
Back to WW2 and the 6th Cdn Div which was raised for service in the Pacific n 1945.This Div was euipped with standard US weapons and US Army training cadres were sent to concentration points and training camps in Canadato provide weapons training.
