Although the following information is about World War 1 records, I am posting it on this Forum as Meurig has previously advised it is worth checking these records, as they “do contain some papers for men who did not serve in WW1” viewtopic.php?f=19&t=7266&start=15#p31162Service and pension records from World War 1
from the National Archives, Kew have been available on the pay site Ancestry.com. for a while. These are British Army WWI Service Records 1914-1920 also called WO 363 records and known as the ‘Burnt Documents, and British Army WWI Pension Records 1914-1920 also called WO 364 records.
These records have recently become available on the free website FamilySearch as images.https://familysearch.org/search/collection/2125045
They are explained in this FamilySearch Research Wikihttps://familysearch.org/learn/wiki/en/United_Kingdom,_World_War_I_Service_Records_(FamilySearch_Historical_Records)
Although the names on the images have not been transcribed, it appears the images are grouped alphabetically, so these records are an alternative if you do not have access to Ancestry
Additional note: When I posted the above information on the Great War Forum, a response said:
"If you go to indexing at the top of the home page and then worldwide indexing project more, halfway down the page, find United Kingdom in the list and you will see they are asking for help indexing these records".
