Of the several Bert Malone's that I found, only one is a real fit. I can find no military service for him.
This is what I did find:

From SSDI: SS# (email me if you want me to send it)

DOB 4-7-1875

DOD 11-15-1971

Last residence 7910 Amarillo, Potter, Tx

SS# issued 1965 in Oklahoma

WWI Draft Registration Index:

DOB 4-7-1875

Residence, Choctaw, Ok.

I don't have him on any of my current lists for Black Regulars, but that is a work in progress, and has only a fraction of those who served.
