I just looked at that one and it is...but very small scale.
I was thinking Silver Bayonet might be the one to "replay" the combat - but that's at too big a scale (at battalion level I think)....anyway the Ia Drang scenario in that game is a few hexes - hardly the details "maneuver" options I was hoping for. Personally I think Company level would be too big for what I am wanting to replay.
I was hoping for something with a lot more tactical options available, including possible reinforcements depending on whether the LZ was held or not...I think I need to look for a game that's got something at platoon level.
Any ideas?
I see '65 might be a fit. Can't see anything else really (modern!)
