We used to run Vietnam games all the time in Manitoba we did both grunt and LRRP games. This was from Operation Green Heat. LRRP team crash landed at night and had to make it through hostile territory to a new LZ to be extracted at first light. We made it to the LZ, it was an overcast night with light drizzle so you couldn't even see your hand in front of your face with VC everywhere looking for the team and lots of close calls.
LRRP team in Manitoba from 2005.

There are still a few of us Nam guys around who play every so often.
