The name of the ruleset is
Force on Force - and is written by the Ambush Alley team and published by Osprey. There are a combination of dice and cards used for unit activations, reaction tests etc.
The Ambush Alley website is here:

There are several scenario books (each of which has detailed OOBs etc):
Ambush Alley - Vietnam
Cold War Gone Hot - Worlds War III, 1986
Day of the Rangers - Somalia 1993
Enduring Freedom - Afghanistan 2001-2010
Road to Baghdad - Iraq 2003
Fallujah - Iraq 2004
There is also
Tomorrow's War which is an adaptation for Sci-Fi gaming. The rules were
really popular a couple of years ago and then settled down as figure gamers moved onto the next craze, Dark Age gaming with
Dux Brittaniarum or
Saga.
As you'd expect with Osprey published works the production quality is extremely high but better than that the rules give a good game too.
