Military Letter for Myron Andrew French

A couple of years ago, my aunt sent me this page that belonged to my great-grandmother's second husband- 

Transcription below 

This document belonged to Corporal Myron Andrew French (1894-1964). I don't know much about him except that he was the son of Alonzo French (1869-1933) & Lucretia Alice Ward (1871-1930). He married my great-grandmother Ruby Mae French sometime after 1972. He was first married to Gailen G. Jett (1898-1923) whom he had 2 daughters with.

I am so perplexed when it comes to this document because I have no idea what it means! 

If anyone can help- please comment or email me Carriesmith11411@yahoo.com

Thanks!!
