Unidentified Photographs – Can you help identify the people or places?

Photo with name Charlie Gray. Unknown service or location but possibly Merchant Seaman. Date unknown but believed to be during 1940S. The only info is that my father knew him but Charlie is believed to have been killed or took his own life. I would love to find who he was etc. Thank you

This photo was taken somewhere in Hampshire; the photographer came from Basingstoke but this does not mean this view is from there. Can anyone help identify where it is, please?
UPDATE: We have now identified this image. Thank you to CRW 7/11/2023

The photo above is of a Royal Marine dated 1905 by the name of Wareham, however there is not enough information to identify who he was. Apparently the photo refers to Royal Marine Legation Guard Football Team. Royal Marines Legation 4 v US Marines Legation 0 played at Seoul, Korea on 13th March 1905
