Yeah- never met my counterparts in Cuba.
But I'm working on that...
When I was in Alaska, we partnered with some of the Canadian Forces (good troops) Did a few jumps together. I was cadre at Northern Warfare school- some of their folks went thru our Mountaineering tng.
The folks I am speaking of still used the No.4 Mk 1 rifle. Reliability under extreme cold, and a big enuff bullet for bear.
