I have came across a discharge paper for my father and am quite baffled. I have his original which states he was discharged on January 8th, 1946. Now I've come across another which states no unit but has his name, serial #, CA_RES (what does this mean?), and states he enlisted on January 9th of 1946 and was discharged on january 8th, 1949.It was signed by a Major Herman Marlow, Cavalry. I have no records of him re-enlisting, if that is what this is. In fact, I have records that show he went to college after the war. Can someone explain what I have here in my possession?
