Various people have adapted the TooFatLardies' company-level rules I Ain't Been Shot, Mum (WW2) and Charlie Don't Surf (Vietnam) for other, more modern periods. Nick Overland, for example, has a set of rules called I Ain’t Been Nuked, Mum; and Egg another called Boris Don’t Surf. There are also the official IABSM supplements B'Maso and Rock the Casbah covering, respectively, the winds of change wars in Africa between 1950 and 1990, and modern urban warfare in the Lebanese Civil War between 1970 and 2000.
Elsewhere in this section of the site, you'll find my own army lists for the Six Day War and Yom Kippur War (along with After Action Reports and a gallery of my figures), below you will find After Action Reports using IABSM, CDS, IABNM or BDS to fight games from the wargames period encompassed by the word Moderns i.e. anything after about 1970.
