If this query is about the North West Frontier of India, I would be very surprised if there were
any British Army “Army Hospital Corps” present, although I cannot quote an actual reference.
There may have been doctors who were part of the Royal Army Medical Corps ( from 1898, or the preceeding Corps) but I think all support personnel would be provided by the Indian Army. I don’t think British troops would have an official role as stretcher bearers- British troops fought, but all manual work in India was performed by native Indians. Europeans just didn’t do manual work.
The following article may be of interest :
"Summary of Operations on the North-West Frontier of India, from 19th June 1897 to 6th April 1898" by Surgeon General AA Gore MD page 446
Army Medical Department Report for the Year 1897 Volume 39 1898 Archive.org
