SASLess, the US decorations were known over here as salad dressing. Just how easy is it for an American to read them?
In UK the sets are virtually discrete, - pip squeak and wilfred in WW1 - a couple or up to 5 or so in WW2 with additional gallantry medals - a handful of Korea and GSM - then the modern clutch from Falklands, Serbia, GW1, GW2, Sierra Leone, and Afg plus a few others. There would be a few overlaps but the majority would be discrete sets worn by hostilities onlys or national service, and the current sets. Even so it is not easy to recognise them all.
My father had 5 and 2 clasps from WW2 and my wife's grandfather had 6, 3 from each war and her father had 5.
