Megan,
The CWGC mandate is just to deal with the two World Wars with providing and maintaining the cemeteries and memorials world wide. There are a few other things like education etc but other conflicts are out of scope, which is one reason for the Armed Forces Memorial at Alrewas which commemorates those killed on duty since 1948.
If you haven't seen the memorial, I strongly recommend a visit when life returns to near normal again.
I am quite pleased that I was able to get a man's name on the memorial after it had been missed off because it was thought he had died of natural causes.
