Grunts, Leathernecks and Charlie Vietnam War Rules
Grunts, Leathernecks and Charlie is a set of free wargames rules set in the Vietnam War. The author writes:
Players who are interested in a FUN and FAST Vietnam game system can consider these rules a flexible framework for use. I designed these rules to be used by both beginners and veteran players. Play can be quick and easy OR made more realistic and slower by adding advanced options. If you do not trust your opponents, then this is not the right rules’ set to use. It will assist any player who has an interesting scenario to run at a convention or at a local shop.
